Image text: Not enough houses on your block? Just hit them at 30-year intervals from here to 2300 and get 10x the candy.
First of all, because Doc Brown uses the phrase "overshot", he is travelling back in time to maximize his candy intake. Which is opposite of the image text which proposes going forward in time to trick or treat as many times as possible.
Secondly, I cannot get the rhyme, "Great Scott, I must have overshot!" out of my head.
EDIT: And as kb says in the comments the character is Emmett "Doc" Brown from the Back to the Future series, who's catch phrase was "Great Scott!".
Climbing
by Jeff
Image text: Where did you even get this wall? Return it there and stand it back up right now.
This comic is about taking a sideways photos of yourself crawling along the ground so it looks like you are climbing a vertical face rock wall. This is a classic camera trick used in movies and television.
The first frame is from overhead of the "climber" and the rest are from the side.
Nachos

Image text: 'Cheater!' 'Hey, gaming on wifi? You have only yourself to blame.'
This is another unclear conversation from xkcd right off the bat. The girl with the white hair calls the house of the girl with the dark hair and the guy. The guy answers and says that "Megan", the girl with the dark hair can't come to the phone because she is gaming. The girl in the white hair knew this already because she was playing against Megan. And probably knew that Megan was gaming over wifi.
Microwaves and wireless routers both transmit at the 2.4GHz range. In the case of microwaves, they use that range to cook food. If some of the waves leak out of the microwave, which they invariably do, they will interfere with a nearby wireless router.
And I agree with the comic wholeheartedly, why would you game over wifi anyway?
NOTE: If you haven't headed over to xkcd.com and witnessed the homage to Geocities that Randall has created, you are missing out.
So Bad It’s Worse
by Jeff
Image text: You think it's so legendarily bad that you'll torrent it and sit through it just for the kitchy nerd cred. I, too, once thought as you did.
The Star Wars Holiday special was so terrible that George Lucas tries to act like it never existed. He gave the rights to "variety TV guys" to create the special and it was widely panned.

More Accurate
by Jeff
Image text: We live in a world where there are actual fleets of robot assassins patrolling the skies. At some point there, we left the present and entered the future.
This is a comic referencing the Terminator series , in which a super-intelligent machine from the future time travels back in time to kill Sarah Connor.
However, we currently have robots that are able to attack specific locations and targets. Originally, unmanned aerial vehicles were only used for surveillance and reconnaissance. But, now more than ever, they are used for attacks. One thing that keeps us short of a Terminator scenario is that most of the unmanned aerial vehicles are either pre-programmed or flown remotely by members of the military. Still, the image text is correct, the future is here.
Bag Check
by Jeff
Image text: A laptop battery contains roughly the stored energy of a hand grenade, and if shorted it ... hey! You can't arrest me if I prove your rules inconsistent!
It's never a good idea to mention what possibly dangerous stuff you have in your bag at the airport. Probably better off just buying a new water after the check point. No matter the inconsitency of the rules. And the joke in the image text is that you can very easily be arrested on inconsistent rules.
Nowhere
by Jeff
Image text: I mean, seriously, NOWHERE? For starters, there are like a thousand species of dinosaur.
Looks like the girl in the comic would rather be riding a dinosaur than hanging out with that dude. Ouch. The rare comic that allows us to use the cynicism, love and dinosaurs tag in one post. Bet that doesn't happen again.
Static
by Mike
Image Text: I firmly believe that nothing can go wrong on a project if you're wearing one of those wrist things.
This comic is making of the fact that the male geek here thinks the anti-static bracelet will work as a contraceptive technique. Anti-static bracelets are used by computer technicians to prevent an accidental static discharge that can damage sensitive electronic equipment.
UPDATE: From the comments it looks like there's some confusion over who is talking in each panel. In my opinion, the girl is always the speech bubble the originates on top (the ones that have the arrows pointing down) and the guy is the one with the arrows pointing up. They are currently trying to have sex and the guy is wearing an anti-static bracelet (where on his body he's wearing it is unclear). Earlier in the week he was replacing RAM and wearing a condom (again, where on his body is unclear).
Fall Foliage
by Mike
Image Text: And I could replace you with older pictures of you, from back when you looked happy.
The hue of an image is the image's color or shade. The hue adjustment in Photoshop lets you move a slider back and forth to shift the colors of the image. This comic is suggesting that instead of taking the typical American trip to someplace like New Hampshire to see the leaves change colors in autumn, one could take a picture of summer leaves and just play with the hue slider in Photoshop to get a similar appearance. Of course, that wouldn't replicate my favorite part- the smell.
Scary
by Mike
Image Text: I'm teaching every 8-year-old relative to say this, and every 14-year-old to do the same thing with Toy Story. Also, Pokemon hit the US over a decade ago and kids born after Aladdin came out will turn 18 next year.
No hidden meaning here, but this sure is scary. I remember graduating college and seeing a banner welcoming the class of 2010. I was half expecting them to be robots. What's being implied here is that time is moving really quickly and we're getting older faster than we think. Events that seem like they "just happened" have happened long enough ago for a whole other person to come into existence, grow up, and learn to carry on a conversation.
