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.

Ricky Gervais was on "The Tonight Show" with Jimmy Fallon and they did "Lip Flip." They probably should've done one of the other games - Ricky would be good at Box of Lies - but every time Ricky laughs you have to laugh. Jimmy looks like a vampire with Ricky's sharp teeth. This line is uttered at one point: "I'm Jimmy Fallon, and I shave my balls." My, my! They also sing some Christmas carols in the end.
Ben Stiller was on "Late Show" with David Letterman, and it's been 22 years since he was first on the show. He said he appreciates Dave having him back since he was "so terrible" the first time. He was so nervous and was prepared for all these questions that Dave never asked. Dave made the mistake of talking to Ben like a human being and it threw him off. Ben even remembers the review he got for such a bad talk show performance. Ben also talked about taking a hot air balloon ride with his family and it did not go well at all.Olivia Munn - beyond stunning - was also on Dave's show, talking about how she doesn't go home to Oklahoma that often. They are a classical Asian family, she said, they love at level 2 as opposed to level 10. Some families are just like that. A lot, maybe.Kathy Griffin was on "Jimmy Kimmel Live," talking about how she's taking over for Joan Rivers on "Fashion Police." She told Jimmy he needs to up his game and stop wearing the same suit over and over again. Kathy also blasted that "lady named Ryan Seacrest," who was on Jimmy's show last week, since Kathy and Anderson Cooper will also be doing their New Year's show opposite Ryan. Kathy said she's going to prank and torture Anderson again. Jimmy vowed to show up and make out with Anderson right there on the show. Kathy also talked about participating in Britney Spears's show, being led around on a leash. They show a clip of it. She said she wasn't allowed to look Britney in the eyes.

Sofia Vergara was on "Conan," talking about how her boyfriend, Joe Manganiello, was in "Magic Mike" and it showed how dangerous it can be to be a stripper, since he got injured. Love all the times Sofia calls Conan "creepy."JB Smoove was also on "Conan," and he said he loves his floor seats at Knicks games, but he's scared of the T-shirt cannons.Michael Sheen was on "The Late Late Show" with Craig Ferguson, talking about how much he loves Medieval Times and Pirate Adventure in Orange County. As a wrap party present to the cast and crew of "Masters of Sex," Michael took everyone to Pirate Adventure. He also surprised his family with a great trip to Medieval Times. Craig wants to join Michael's family now. It does sound fun.
Ben Schwartz ("Parks and Rec") was also on "The Late Late Show" and he shared his idea for Craig's final scene of the show. It involves the snake mug and Morgan Freeman. Classic.Rosario Dawson was on "Late Night" with Seth Meyers, talking about working with Chris Rock, Tracy Morgan and Leslie Jones in "Top Five."
