interesting.. i see all these letterman and leno lovers, yet o'brein beats them both by double the votes..
btw, letterman, obrein, a monkey sitting there doing nothing, then leno... letterman is, by far, the best late night t.v. show host ever
edit: i never really had a chance to watch carson, since he's before my time.. so i guess ever was kinda pushing it.. but from what i've seen of carson, letterman is still better..
