The humor is in the details.
I'm not sure how Gary Larson gets away with all he gets away with. Cannibalism, infant death, suicide, nuclear war, torture, friendly fire, people with big noses... he pokes fun at them all. As someone with a relatively large schnooz, who is also becoming more liberal, I take offense to at least two of these. How does he get away with it all? How? I mean, buddy - there's the line - WAAAAYYY back there. You're not just edging over it. You're two states past it. And it's all so funny. What's that say about me - that I find big nose jokes and nuclear meltdown jokes funny? Hopefully it says that I have a healthy sense of humor. Hopefully it doesn't mean that I'm a psychopath.
The humor is in the details.
I found this the most true in a cartoon with a bunch of scientists. The caption: "Testing whether or not animals 'kiss.'" Prominently, in the center, there is a man kissing an aardvark. A bunch of scientists are gathered around - two with clip boards, and one writing on a chalk board. That would be funny enough. But in the back, you have a cow punching a man, and his glasses are flying off. (Apparently, cows do NOT kiss...) And on the chalk board, written in cursive: "Armadillo Looks like rejection
doesn't want anyone
Squid Couldn't find lips
No response
nothing lateif study pro..." (Some of that was scribbles...)
I love the cow and chalk board in the back ground. That added detail is great. And funny.
Why is it funny? I don't know. But it is. And so is Larson. Maybe inappropriate. Maybe not. Definitely funny.
