Title text: A breadth-first search makes a lot of sense for dating in general, actually; it suggests dating a bunch of people casually before getting serious, rather than having a series of five-year relationships one after the other.
When doing a blind search in computing, there are two main tactics - depth-first search, and breadth-first search. Depth-first search, as indicated in the comic, means going as far as you possibly can before looking at other possibilities. This turns out to be a bad idea: instead of preparing for his date, as he should have been doing, he instead spent the whole time doing research on snake venom, to the exclusion of even getting dressed. By contrast, a breadth-first search will look only minimally into a topic before moving on to another; any new depth exposed by this minimal check will be added to a list of stuff to do later. This would have allowed the man to briefly check many more things within the time allotted, and probably still have been able to get dressed.
LD50, or median lethal dose, is the dose of a toxin required to kill 50% of the population studied, usually expressed in milligrams of toxin per kilogram of body mass. The inland taipan's venom does, indeed, have highest median lethal dose among snake venoms. (Fortunately, it is extremely shy in temperament, and will always escape danger rather than bite if it can, which is why it isn't considered to be a particularly dangerous snake.) Incidentally, corn snakes and garter snakes are not even remotely dangerous to humans (in fact they're the most popular pet snakes), and of the four different species commonly known as "copperheads," the only dangerously venomous one is Deinagkistrodon acutus or sharp-nosed viper.
The relationship advice given in the title text should probably not be taken too seriously, even though one might be more sure about what kind of person one is looking for after already having dated a few people.
- Preparing for a date:
- [A man with wet hair and a towel around his waist thinks with his hand to his chin.]
- Man: What situations might I prepare for? 1) medical emergency, 2) dancing, 3) food too expensive...
- [Close-up on man's face.]
- Man: Okay, what kind of emergencies can happen? 1)A) snakebite, B) lightning strike, C) fall from chair...
- [Still thinking...]
- Man: Hmm. Which snakes are dangerous? Let's see... 1)A)a) Corn Snake? b) Garter Snake? c) Copperhead?
- [Sits down in a chair with a laptop, still wearing towel.]
- Man: The research comparing snake venoms is scattered and inconsistent. I'll make a spreadsheet to organize it.
- [Bottom panel is larger than top four, and aligned to right.]
- [Ponytail meets the man on his front stoop. She is carrying a purse, and looks down at his towel. The man holds his arms in the air triumphantly.]
- Ponytail: I'm here to pick you up. You're not dressed?
- Man: By LD50, the Inland Taipan has the deadliest venom of ANY snake!
- Caption: I really need to stop using depth-first searches.
