<div>I somehow has the feeling that the business-plan behind is that people will pay you that the drone LEAVES. --[[User:DaB.|DaB.]] ([[User talk:DaB.|talk]]) 08:39, 3 May 2013 (UTC)<br />

<br />
:: Even if this is the revenue model, it would be an undertaking that still genera...err.. extorts revenue. So, the drone is still incorrect when it yells out in the last panel. On the other hand, we're back to square one (the definition of business) if it's not the blackmailing BlackHat you pay to get rid of his drones, but another business that shoots them down.

<br />
The "as it does not seem to generate money" bit seems a bit premature in the explanation. At the stage he's questioning whether it ''is'' a business, the question is "''who'' would even pay?". Only in the last frame does the utter lack of generated money (above idea from DaB. aside) arise and make him assert that it is ''not'' one, which gets him shouted at. Not sure how to re-write it, though. [[Special:Contributions/31.110.91.76|31.110.91.76]] 09:59, 3 May 2013 (UTC)<br />

I think this could also be to do with how Google Now works - e.g. it will often tell you things that you are semi-aware of, but ignoring.--[[Special:Contributions/194.201.25.22|194.201.25.22]] 12:03, 3 May 2013 (UTC)<br />

Google will make money on Now the same as always. By renting our eyeballs. I used it for the first time last night. It located me and showed me nearby businesses. If they weren't paying for clickthrough then, they will over time. ''&mdash; [[User:Tbc|tbc]] ([[User talk:Tbc|talk]]) 12:42, 3 May 2013 (UTC)''<br />

: I have not seen those yet, maybe because I'm living in a rural area. But it always shows me the weather, upcoming appointments (and when to leave for them) and traffic on my way to work. At work (smaller city) it also shows me places nearby to visit, but no ads, only POIs. --[[User:SlashMe|SlashMe]] ([[User talk:SlashMe|talk]]) 15:17, 3 May 2013 (UTC)<br />
<br />
::Yes, and how do you think Google determines *which* POIs to show you? It's essentially an ad that's embedded so deeply into the user experience that you don't even realize it's an ad. [[User:Orazor|Orazor]] ([[User talk:Orazor|talk]]) 05:46, 25 September 2014 (UTC)<br />

The bit about "must nake money" being WRONG is probably a reference to the scores of dotcoms who came to market with the idea that "We'll make something cool now, figure out how to make money from it later" [[User:Gardnertoo|Gardnertoo]] ([[User talk:Gardnertoo|talk]]) 13:30, 3 May 2013 (UTC)<br />

Of course the Pakistani version of this drone shoots you (and/or your relatives) if you say something silly, unless you pay it enough money. ~~tbwtg~~<br />

I think that this explanation is wrong. This strip is about giving too much privacy. Google or Facebook knows much more about us than anybody else, and information is money, so this IS a huge business even if you dont pay anything --[[Special:Contributions/89.70.180.131|89.70.180.131]] 23:43, 3 May 2013 (UTC)<br />

Any good business makes decisions to please or entice it's paying customers. You are not google's customer, or facebook's. If you didn't pay, you're not the customer, you're the stock-in-trade. The hardware store owner doesn't ask the hammers where he should display them. The grocer doesn't ask the watermelon for advice on marketing policy. ~wrybred<br />
<br />
So the Innocence Project, say, has wrongly convicted prisoners as its stock-in-trade (since they don't pay for the representation). So, following the money trail, it must be the *donors* to the Innocence Project who are the clients, since they are paying. So the IP attorneys should consult with the donors about the defense strategy, not the prisoners. In fact, attorney-client privilege in this case must cover communication between the IP attorney and the donor, not the prisoner represented. It's all so clear to me now!

:I don't think your analogy quite holds up, <s>and I'm not entirely sure about the point you are trying to make</s>. (NOTE: sorry -- didn't mean to make that sound so deprecating. Please help me to understand your point.)<br />
<br />
:The relationship between a lawyer and the person/entity s/he represents is a little bit (and by little bit I mean a lot) different from that of a company and its share holders. I think the question in this case is to whom the fiduciary duty is owed. And for a lawyer, it is always his or her client. Sure, donors to IP keep the organization running, and *maybe* the lawyer might consult with the board of directors (or whatever steering comittee structure IP has set up) to determine whether to take a particular case. Once that case is selected and the prisoner agrees, however, the attorney/client privilege only exists between the lawyer and the prisoner in this case. As an aside, I'm sure IP does employ a staff attorney(s) whose sole job is to look out for IP's interests, and with whom an attorney/client privilege exists. But that's a different story. While corporations only care about money, that's not *always* true for lawyers. [[User:Orazor|Orazor]] ([[User talk:Orazor|talk]]) 05:46, 25 September 2014 (UTC)<br />

<br />
==Explanation==<br />
When a group of people go together to any kind of event where they expect to drink alcohol, and would like to drive to and from the event, it is usual to select one who has to be the '''{{w|designated driver}}'''. This person will then stay sober during the event, and can thus safely drive the other people home afterwards disregarding how drunk the other people becomes.<br />
<br />
However, as this comic points out, if it not a simple task of going from A to B and back, all together at the same time, then it becomes an complex problem that requires an intricate kind of strategy and logical thinking to solve. And may need more than one driver.<br />
<br />
In this comic [[Cueball]] addresses his friends, ([[Megan]] and two other Cueball-like guys), regarding this problem right before they enter a bar. It seems they have already decided that one of the friends (Tom) will be the designated driver. But then Cueball mentions that they will have to leave in two groups. And for some reason one of these groups will need at least two drivers (this is hard to explain - see below under [[#Number of drivers|number of drivers]].) So now they already need three designated drivers. Furthermore someone has to go and pick up Paul. (This could be one of the designated drivers though). And also two girls (Julia and Emily) have to leave earlier than the rest by 10:00. (That could then be be one of the two groups that Cueball mentions, and then one of these girls should drive). <br />
<br />
In the third panel the situation seems to be illustrated. Three people are drawn outside the bar with three lines going to the bar, so the number of lines leaving and entering each destination seems to represent a person each. Since the number of people leaving and entering each destination is the same, this makes it seem like the diagram is intended to be accurate. There are four people entering and exiting the bar and six people entering and exiting both the party and the dinner. The confusing part of the diagram is that there are only three people at the bar to begin with, not the four shown in the first panel. It also seems strange that someone will go back to the bar and especially that another goes back to the dinner from the party. It is thus not easy to make the diagram fit the description. See below for a possible take on [[#The chart|the chart]].<br />
<br />
But the general concept would be that some people meet at a bar before joining the rest of a group at dinner, then later most of these move on to a party. After the party (or bar/dinner) people are going to head home in different groups. <br />
<br />
The enormous complexities of planning who {{w|car pool}}s with whom, from where to where, and when, make an excellent logic puzzle. And what is worse, anyone who has to drive needs to stay sober. So it is important to solve the puzzle before the drinking starts, or else there will be too few that can drive, or too many who never get to drink.<br />
<br />
To make matters worse the last Cueball-like guy complicates this already complicated {{w|logical puzzle}}, by involving the classic logic puzzle of the {{w|Wolf, goat and cabbage puzzle|wolf, goat and cabbage}}. In the last panel the guy is shown standing with a goat on a tether, saying he can't be in the car with the wolf. Cueball is then brought to swearing over this. (The goat puzzle was also the subject of [[1134: Logic Boat]]). This must mean that one of the people who has yet to arrive comes with a wolf. And this may go some way of explaining why there needs to be a [[[[#Number of drivers|number of drivers]]]. But since it did not seem like Cueball was thinking about this fact when he mentioned this, that cannot be the explanation.<br />
<br />
The title text makes it clear why ordering a taxi is out of the question as it would take money out of the beer budget. Of course it also cost money to use your own car for gas etc. But when you already have a car, it is always cheaper to use that than pay for a taxi.<br />
<br />
===The chart===<br />
Since the first panel must take place before any drinking takes place, to make the title of the comic make sense, then there is already missing one from the bar, since we know that there are four at the bar at the start of the comic. To make the diagram fit the fourth person should then be the one coming from the party. But he would thus come from there before anyone else arrived at the party. And then someone will have to leave directly from the bar without going to the dinner or party, since no one will come back later. And since Julia and Emily leave together, this cannot be either of them. That would also mean that only five leave the party since one of the leaving arrows was the fourth to get to the bar early. And there are six arriving, all of which must be assumed to arrive later yet. And since no one enters the party from outside, someone must have been at the party site from the start and would stay there afterwards. <br />
<br />
All this will at first make very little sense, so in the end it does not seems likely that the diagram in any way can represent the situation precisely. Except if the party is thrown by one of the guys, and he starts and finishes there. Here below is a possible explanation that would explain all the information and the chart. It this was at all intended to be possible by [[Randall]] is not certain but it fits:<br />
<br />
*The three people outside the bar are the one represented on the diagram.<br />
**Two Cueball-like guys of which the last one is Tom, the designated driver, and Megan represents one of the girls mentioned later Emily or Julia. <br />
**They arrive together to the bar. <br />
*Here they meet Cueball. <br />
**It is Cueball who throws the party. So the party is at his place, and he has arrived at the bar from there. <br />
**There is thus no arrow entering the party for him to begin with, as he lives there. <br />
*There are now four at the bar. <br />
**Later Cueball will take a route past his house (the party place) before going to the dinner. <br />
**Two of the other three in the bar will go straight to the place of the dinner. <br />
**The last in the bar is the one who has to go after Paul. He thus leaves the chart. <br />
*The guy who picked up Paul will return together with him to the dinner as the two arrows coming in from the top. <br />
*The second girl (apart from Megan) is the last long arrow coming in alone from the right. <br />
*Now all six people are at the dinner. <br />
**After the dinner one of these six people (a guy) will leave alone<br />
**The other five including Cueball will continue to the party at his house. <br />
*There are thus five at the party but only four of these leaves afterwards in two groups of two. <br />
**Two of these are the girls that leaves already at 10:00 leaving only three guys in the house. <br />
**When the two last leave Cueball will stay at home, thus explaining why only four leaves.<br />
<br />
===Number of drivers===<br />
The chart offers no solution to the puzzle of why a single group would need more than one driver. As neither of the groups leaving the party is more than two people it would be hard to get more than two drivers. And hard to explain why there would be need for more than one.<br />
<br />
The only time more than two lines are following each other from one place is the three that arrive together at the bar and the five that move from dinner to party. And even five people can normally fit in one car.<br />
<br />
Of course when we begin to take into account that one of them has a goat and one of the others have a wolf, then there are suddenly eight living beings that needs transport. And this may explain the need for two cars. But still not the more than one driver for a single car.<br />

However, as this comic points out, if it not a simple task of going from A to B and back, all together at the same time, then it becomes an complex problem that requires an intricate kind of strategy and logical thinking to solve. And may need more than one driver.<br />
<br />
In this comic [[Cueball]] addresses his friends, ([[Megan]] and two other Cueball-like guys), regarding this problem right before they enter a bar. It seems they have already decided that one of the friends (Tom) will be the designated driver. But then Cueball mentions that they will have to leave in two groups. And for some reason one of these groups will need at least two drivers (this is hard to explain - see below under [[#Number of drivers|number of drivers]].) So now they already need three designated drivers. Furthermore someone has to go and pick up Paul. (This could be one of the designated drivers though). And also two girls (Julia and Emily) have to leave earlier than the rest by 10:00. (That could then be be one of the two groups that Cueball mentions, and then one of these girls should drive). <br />
<br />
In the third panel the situation seems to be illustrated. Three people are drawn outside the bar with three lines going to the bar, so the number of lines leaving and entering each destination seems to represent a person each. Since the number of people leaving and entering each destination is the same, this makes it seem like the diagram is intended to be accurate. There are four people entering and exiting the bar and six people entering and exiting both the party and the dinner. The confusing part of the diagram is that there are only three people at the bar to begin with, not the four shown in the first panel. It also seems strange that someone will go back to the bar and especially that another goes back to the dinner from the party. It is thus not easy to make the diagram fit the description. See below for a possible take on [[#The chart|the chart]].<br />
<br />
But the general concept would be that some people meet at a bar before joining the rest of a group at dinner, then later most of these move on to a party. After the party (or bar/dinner) people are going to head home in different groups. <br />
<br />
The enormous complexities of planning who {{w|car pool}}s with whom, from where to where, and when, make an excellent logic puzzle. And what is worse, anyone who has to drive needs to stay sober. So it is important to solve the puzzle before the drinking starts, or else there will be too few that can drive, or too many who never get to drink.<br />
<br />
To make matters worse the last Cueball-like guy complicates this already complicated {{w|logical puzzle}}, by involving the classic logic puzzle of the {{w|Wolf, goat and cabbage puzzle|wolf, goat and cabbage}}. In the last panel the guy is shown standing with a goat on a tether, saying he can't be in the car with the wolf. Cueball is then brought to swearing over this. (The goat puzzle was also the subject of [[1134: Logic Boat]]). This must mean that one of the people who has yet to arrive comes with a wolf. And this may go some way of explaining why there needs to be a [[[[#Number of drivers|number of drivers]]]. But since it did not seem like Cueball was thinking about this fact when he mentioned this, that cannot be the explanation.<br />
<br />
The title text makes it clear why ordering a taxi is out of the question as it would take money out of the beer budget. Of course it also cost money to use your own car for gas etc. But when you already have a car, it is always cheaper to use that than pay for a taxi.<br />
<br />
===The chart===<br />
Since the first panel must take place before any drinking takes place, to make the title of the comic make sense, then there is already missing one from the bar, since we know that there are four at the bar at the start of the comic. To make the diagram fit the fourth person should then be the one coming from the party. But he would thus come from there before anyone else arrived at the party. And then someone will have to leave directly from the bar without going to the dinner or party, since no one will come back later. And since Julia and Emily leaves together, this cannot be either of them. That would also mean that only five leaves the party since one of the leaving arrows was the fourth to get to the bar early. And there are six arriving, all of which must be assumed to arrive later yet. And since no one enters the party from outside, someone must have been at the party site from the start and would stay there afterwards. <br />
<br />
All this will at first make very little sense, so in the end it does not seems likely that the diagram in any way can represent the situation precisely. Except if the party is thrown by one of the guys, and he starts and finishes there. Her below is a possible explanation that would explain all the information and the chart. It this was at all intended to be possible by [[Randall]] is not certain but it fits:<br />
<br />
*The three people outside the bar are the one represented on the diagram.<br />
**Two Cueball-like guys of which the last one is Tom, the designated driver, and Megan represents one of the girls mentioned later Emily or Julia. <br />
**They arrive together to the bar. <br />
*Here they meet Cueball. <br />
**It is Cueball who throws the party. So the party is at his place, and he has arrived at the bar from there. <br />
**There is thus no arrow entering the party for him to begin with, as he lives there. <br />
*There are now four at the bar. <br />
**Later Cueball will take a route past his house (the party place) before going to the dinner. <br />
**Two of the other three in the bar will go straight to the place of the dinner. <br />
**The last in the bar is the one who has to go after Paul. He thus leaves the chart. <br />
*The guy who picked up Paul will return together with him to the dinner as the two arrows coming in from the top. <br />
*The second girl (apart from Megan) is the last long arrow coming in alone from the right. <br />
*Now all six people are at the dinner. <br />
**After the dinner one of these six people (a guy) will leave alone<br />
**The other five including Cueball will continue to the party at his house. <br />
*There are thus five at the party but only four of these leaves afterwards in two groups of two. <br />
**Two of these are the girls that leaves already at 10:00 leaving only three guys in the house. <br />
**When the two last leave Cueball will stay at home, thus explaining why only four leaves.<br />
<br />
===Number of drivers===<br />
The chart offers no solution to the puzzle of why a single group would need more than one driver. As neither of the groups leaving the party is more than two people it would be hard to get more than two drivers. And hard to explain why there would be need for more than one.<br />
<br />
The only time more than two lines are following each other from one place is the three that arrives together at the bar and the five that moves from dinner to party. And even five people can normally fit in one car.<br />
<br />
Of course when we begin to take into account that one of them has a goat and one of the others have a wolf, then there are suddenly eight living beings that needs transport. And this may explain the need for two cars. But still not the more than one driver for a single car.<br />

==Explanation==<br />
When a group of people go together to any kind of event where they expect to drink alcohol, and would like to drive to and from the event, it is usual to select one who has to be the '''{{w|designated driver}}'''. This person will then stay sober during the event, and can thus safely drive the other people home afterwards disregarding how drunk the other people becomes.<br />
<br />
However, as this comic points out, if it not a simple task of going from A to B and back, all together at the same time, then it becomes an complex problem that requires an intricate kind of strategy and logical thinking to solve. And may need more than one driver.<br />
