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.

This is it. The end of an era. Wednesday, May 20 was all about David Letterman's retirement from late night TV after 33 years, and his final night as host of "The Late Show." Stephen Colbert will take over "Late Show" on September 8. You should head to TheLateShow on YouTube to catch up on all the videos posted from the past few weeks, but here are the main segments from last night -- if nothing else, you should watch the epic star-studded Top 10 list.

Here's Dave's final show entrance, with the crowd standing to cheer: Dave's final monologue started after he forced the audience to calm down and stop chanting for him. He said they stood so long they didn't have time for the "gifts to the audience" segment. He also revealed the bad news: "I'll be honest with you, it's beginning to look like I'm not gonna get 'The Tonight Show.'" Haha. Also, he's sick of being asked what he's going to do when he's retired, but he took a moment to reveal (joking, of course) his plans: There had to be a last Top 10 list, so here's "Top Ten Things I've Always Wanted to Say To Dave," with each one read by a different celebrity: Alec Baldwin, Barbara Walters, Steve Martin, Jerry Seinfeld, Jim Carrey, Chris Rock, Julia Louis-Dreyfus, Peyton Manning, Tina Fey, and Bill Murray back with No. 1: There was a video with U.S. Presidents noting that "Our Long National Nightmare Is Over" ... capped by President Obama and Dave: Here's "The Best of David Letterman and Kids": Dave very briefly wished good luck to Stephen Colbert -- who must know he has big shoes to fill. Foo Fighters performed "Everlong," accompanied by highlights from Dave's 33-year late night career: And here's Dave's final thank you and good night, after 6,000 shows, asking people to save some of this merited or unmerited praise for his funeral: Other stuff happened on late night TV beyond Letterman's final show. In case you didn't see it before, here's Seth Meyers recreating Letterman's "Late Night" opening from 1982: Patton Oswalt was on "Conan" and he and Conan O'Brien talked about being inspired by David Letterman. There were a lot of "Star Wars" comparisons. When it came time for "Conan" to hit the same timeframe as "Late Show," Conan O'Brien told everyone to record "Conan" but change the channel to watch "The Late Show." Very cute. Respect. Over on "The Late Late Show with James Corden," James had his own Top 10 list, called "The Top 10 Things We Will Miss About David Letterman": James closed his episode with a classic Letterman move - dropping watermelons off the CBS roof: Halle Berry and Jeffrey Dean Morgan were both on "The Late Late Show" and they too talked about Letterman: Also, here's another round of James' Carpool Karaoke -- this time with Justin Bieber and James singing "Baby." Over on "The Tonight Show," Jeff Foxworthy hosted a special edition of "Are You Smarter Than a 5th Grader" with Pitbull and Jimmy Fallon. David Duchovny was also on Fallon's show and revealed he was "The Head Boy" in high school. Dwyane Wade was on Seth's show and talked about being a Groomzilla. Kellan Lutz was also on Seth's show and talked about being an inventor with his fifth patent:
