I will pick a raft of cartoons. And then later, it'll come time to run this cartoon. And I'll look at it, and I won't quite get it anymore. Because sometimes the grenade goes off in the moment, and then it doesn't repeat down the line.
There's public humor, and there's private humor, and they're all appropriate in their own way, and you shouldn't - just as you wouldn't have a megaphone and say certain things that you would say around your friends - things that are perfectly all right within your close social group with whom you share a certain context.
Cartoons are like fruit flies. Biologists use fruit flies because their large chromosomes and short life cycle make them ideal for studying hereditary changes.
One question about a joke is, how well is the strangeness of the situation resolved? At 'The New Yorker', we retain a lot of incongruity, tapping the playful part of the mind - Monty Python-type stuff. We also try to use humor as a vehicle for communicating ideas. Not editorial comment, but observation.
Professional humorists and cartoonists have to go through a stage in which they have to kill their own internal editor just so they can get stuff out. So whether they believe it or not, they need me on the other end to do that editing for them.
