Of course Carson, Letterman Leno.
I don't understand why Fallon is so great, he giggles like a school girl when he interviews, and don't even ask about Seth Myers, WOW, seems like eleven year old boys are in charge of late night programming at NBC.
Kimmel was funny when he was on The Man Show, I only watch him when he has someone on I want to see, I've seen the clips where celebs read the bad tweets about themselves, that's funny.
