If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

David Letterman's very first guest -- 33 years ago -- and he was also his last, Tuesday night on "Late Show with David Letterman." Dave's final show is tomorrow but it'll be a celebration send-off; this is the last classic round of guest interviews. Bill arrived for his big moment by popping out of a giant "Goodbye Dave" cake. He hugged Dave, then visited the band and went into the audience to smear people with cake. In his cake-covered sit-down interview, Bill told Dave they all just want more from him. He got the audience to chant "More! More! More! More!" Then he went outside to face the crowd and gathered them in the streets of NYC to chant "All we are saying is more Worldwide Pants," which is Dave's production company. Gotta love Bill Murray. They also aired a highlight reel of Bill's best moments from 22 years on "Late Night": Bob Dylan also performed "The Night We Called It a Day": Jimmy Fallon offered his Letterman tribute on Monday night, and Tuesday it was Jimmy Kimmel's turn. Kimmel choked up very early in the tribute and cried talking about how he grew up watching Dave's show, describing what made it different from every other talk show. Jimmy also showed a photo from his 16th birthday party -- he had a Late Night cake and wore a Dave Letterman letterman's jacket and they showed his L8 Nite vanity plate for his first car. Kimmel choked up again when saying he wouldn't have his own show if executives and producers hadn't seen him perform on Dave's show. Kimmel said they'll be airing a repeat episode tomorrow night so as not to compete with Dave's final show, and he encouraged his fans to not even watch that. Just watch Dave.

George Clooney was a guest on "Jimmy Kimmel Live," talking about his many pranks over the years. Britt, who was eliminated as one of the new "Bachelorettes" last night, was also on JKL, talking about her disappointment. Jamie Foxx was on "The Tonight Show" and he got the audience chanting "America" -- the audience was filled with Army, Navy, Air Force and Marines. He mentioned running into Meredith Vieira, saying his beard is dyed, so when he hugged her, he gave her "half of a black man's beard." He turned that into a song and did a little dance. Jamie also played "Wheel of Musical Impressions" with Jimmy: Lisa Kudrow and Zach Woods were on "The Late Late Show with James Corden" and they talked about their childhood neuroses.
