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.

Jimmy Kimmel was on repeats Monday night, but David Letterman's show is still winding down so he's all new. On Monday night, Howard Stern was Dave's guest. Howard asked about Jay Leno, to see if he would be on Dave's final show. It sounds like Letterman's team asked Jay and Jay said no. Dave said Jay asked him to be on his own show for the final episode, and Dave said it was a lovely offer but he thought the show should be more about Jay. Dave thinks Jay now feels the same way about Dave's final show.

Dave also showed an embarrassing old photo of Howard, and Stern told a story about previously going on Dave's show and getting no response - even his own parents and listeners didn't see it. "Thank God it's over." Dave and Howard also discussed their best guests ever. Good talk. In the second video, Howard - showboating through the whole interview - stood up to share his disappointment that Dave was going out to dinner with Don Rickles after the show, and they didn't invite Howard. Then Howard brought Dave out in the open stage and basically groped him to try and get a kiss goodbye. "Kiss me! Kiss me now!" Sexual harassment! "Conan" had an interesting Monday. Jean-Claude Van Damme - aka The Muscles From Brussels -- recreated his "Kickboxer" dance scene. He also said there will be a "Kickboxer 2." Also on "Conan," "The Vampire Diaries" star Nina Dobrev talked about her Instagrammed cross-country road trip (she's in the middle of it and just paused to fly out and do this show) and did some splits with Conan O'Brien. Charlize Theron was on "The Tonight Show" and she and Jimmy Fallon chose each other's outfits and gave each other characters to play. It was weird. Jimmy couldn't figure out whether he was meant to be a man or a woman. (Charlize said he was a woman, and even named her.) Charlize had a potty mouth and had to be bleeped at one point. Late in the video, they went over to join the Roots and Charlize pretended to play guitar. If they weren't high through this, they should probably say they were anyway. Dumb. Louis C.K. was on "Late Night with Seth Meyers" and Louis talked about how he wrote for "Late Night" when Conan O'Brien was the host. Louis and another writer slipped in a joke about Conan getting a pearl necklace. It's not a great joke even if you get it. This Sunday is the final episode of "Mad Men" and Seth did a great video on the "Mad Men" previews that tell you NOTHING about the next episode. Here's "The Best of 'Next Week on Mad Men.'" This is an accurate representation of what they're like. Mark Harmon and Zoe McLellan were on "The Late Late Show with James Corden" and James pushed Mark for spoilers on who will be killed off "NCIS."
