We used to get 27, 28 minutes to do a story in, and now they're lucky if they get 18 or 20 minutes. So I don't think they can really do a beginning, a middle, and an end anymore. There's an awful lot of one-line jokes; almost every line is a punchline. It's not the same, but there's still good comedy around.
There aren't many pratfalls in comedy anymore.
I did a guest shot on a comedy series where they did 20 to 30 takes of everything. It's just gone by then. The joke is over. It's not funny anymore, and then of course, the editor's the one that has to figure out the timing. I think a lot depends on that.
I found doing that kind of comedy without an audience is just... for me, it's almost impossible. You need the audience to do their half of the work.
