Colbert pays tribute to Fallon on Jimmy's first night - runs from 1:38 - 1:58:
I was pulling for Bob Sagat or Sarah Silverman to take over from Letterman, but alas, my write-in campaign didn't work (I forgot to click "send" on my e-mail).
Have luck Stephen Colbert!
I think Fallon is going to reign as late night king for some time. He's funny and quite talented (he can dance, sing, play guitar, act, does good stand-up, sketch, and improv comedy, and above average impressions), plus the Tonight Show has very good writers, and Jimmy has a decent sidekick, and a truly kickass band (The Roots).
I don't think Seth Meyers is going to be around for very long. I predict a female will get his slot eventually (Amy Poehler, another Lorne Michaels performer, after Parks and Recreation ends, or perhaps Tina Fey?).
