In before "zomaigawd mai humour is teh bettar th3n ur humar!" Whether it's a culture thing (which it most likely is), a personal preference, or just trying to find something to laugh at, humor is best understood by someone who's grown up around it. You wouldn't find physical comedy funny unless you were getting hurt all the time; you wouldn't find the suicides of mass amounts of people funny unless you used the internet. Weird world? No, just weird people.

I don't usually stay up to watch late-night, but when I do, it's always Letterman, and then Conan. In one sense, it's politics, and in another, it's rediculouslessness to a point where it's funny. Leno isn't funny, and the only true thing about him is that he's big, he has these outrageous mannerisms and deliveries that just are not funny. I don't listen to the interviews, either, but I like how Letterman does things.

Should I have just copied Roto's post for the second part? Yeah, probably.
