> I have noticed an interesting phenomenon in situation comedies. The characters in them rarely laugh. For how much we might laugh and for how many jokes they make, the characters don't seem to enjoy each other's humor much. In fact, when they do laugh, it is usually a mocking, loud laugh, not a genuine chuckle. I think this is my evidence for why TV is not real life because if it were, we'd see more people laughing real hard, rolling off the couch, until no sound comes out. Well, at least my friends would be doing this.

I always used to wonder about that too. People wiser than me claimed that it was because you shouldn't laugh at your own jokes because it ruins the joke. But I know of one standup comic who laughs at nearly everything he says, and it just makes his routine funnier. I can't remember his name unfortunately.
