I second Jon Stewart. That’s the only show that consistently cracks me up.
After that, I usually flip over to Letterman. Some of his bits are clever, like Biff Henderson’s stuff, the Top Ten lists. Or sometimes he’ll do completely off-the-wall stuff, like guys trying to shoot baskets from rooftops or stuffing guys in Santa suits into coffeeshops. Dave sure seems like he’d be a real asshole in person, though.
I hardly ever watch Leno, I just don’t think he’s funny. Sometimes the headlines are, but usually it’s the same jokes over and over. The “funny wedding names” shtick is not funny anymore. “Jaywalking” and everything else just seems to be, “look how stupid everyone else is.” Oh, and Kevin Eubanks really needs to lay off the pipe.
I can’t stay up late enough for Conan. From the little bits that I’ve seen and heard about, I guess all he’s capable of is insulting people as well.
Watched Kilborn maybe once. Painfully unfunny.
Never watched Jimmy Kimmel’s show. Didn’t even know Carson Daly had a show.
