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.

Dax Shepard was on "Conan" Monday night (October 13), and you have to watch his talk about shaving his butt. Conan O'Brien asked about Dax's graphic full nude scene in "This Is Where I Leave You." Was it nerve-racking? Dax said he and Conan suffer from tall white guy syndrome - they have no butt cheeks. He did a lot of lunges and squats to prepare his butt. Dax said he doesn't have any hair on his butt cheeks but - as Andy Richter helpfully put it - "there's a forest in the valley." Dax added that his deep fear was that it would look like a werewolf trying to escape his butt crack. So he asked his wife Kristen Bell to help him, um, trim the forest. It was a terrible experience and he didn't want to give it to a stranger. Kristen was humming "Funkytown" as she trimmed him. The whole story is hilarious.
Shia LaBeouf, who is in the upcoming movie "Fury," was on "Jimmy Kimmel Live" (with his new facial hair) talking about how all the guys in the cast tried to impress Brad Pitt. However, they were also forced to fist-fight with each other, which Shia said was a great bonding experience. Jimmy mentioned that his tooth is missing in the movie and Shia said that's real. He said he got the tooth removed for the movie. That was a real mission to take it out, he said. He found a guy in Reseda next to Radio Shack. He didn't ask too many questions. Haha.

Jimmy also noted that Shia seemed to go crazy since the last time he saw him. Shia talked about his arrest at the musical "Cabaret." Shia said he was coming back from Ireland visiting his girl. When you go to Italy you eat spaghetti, in Ireland you drink whiskey. He was drinking a lot during the World Cup ... then story goes on and on. You just have to listen to him tell it, then decide whether you believe it or not. It seems just a wee bit embellished.

Michelle Monaghan was also on "Jimmy Kimmel Live," promoting "The Best of Me," and she talked about the tiny Iowa town she grew up in and the charm of small-town parades. She also casually mentioned that she used to wrestle hogs. "I'm a blue-ribbon holder!" Nice! Her hair looks good like this, too, don't you think?

Zach Galifianakis was on "The Tonight Show" with Jimmy Fallon and you can see how much weight he's lost. He looks great. But don't ask him about it, 'cause he'll just quip, "I'm dying." He also talked about just welcoming a baby boy; he realized when they were bathing once that his son's testicles fit perfectly in his belly button. There is a God! Zach also discussed his new movie, "Birdman," which was shot in only 30 days.
Also on "The Tonight Show," Casey Wilson shared her worst date story. She also talked about how she got married over the same weekend as Kim Kardashian and Kanye West, so she added Kimye to her own wedding. She then shared a great story about her father's Christmas gift. It'll make you smile - and laugh. Good stuff.

Over on "Late Night with Seth Meyers," Seth talked about Bill Hader's return to "Saturday Night Live" and how he was slightly hurt when he saw Stefon with two other guys on Weekend Update, but he always knew that was the deal when he married Stefon. Speaking of SNL, Fred Armisen was on the show, saying he opened a summer camp for cats. GENIUS. It's one where they get to just visit the suburban Chicago area. A lot of animals can't afford to travel and get to know other cities. Fred is one of the counselors, along with some cool, jaded older cats. Fred = amazing.

Russell Brand was on "Late Show With David Letterman" to talk about his book, "Revolution." The man just talks so fast and loud like he's doing a monologue for a Broadway show and has to play to the back of the house. Manic! Dave talked about Russell's past, he's been clean for 11 years.
Dave Grohl of Foo Fighters was also on Dave's show, talking about his 10-week-old daughter. He also has two other daughters, ages 8 and 5. His 8-year-old loves music. Sometimes his daughters' musical tastes are questionable. When Violet was 2 or 3 she would love to sing the "Rehab" song. Then a different "Rehab" song. The story goes on, it's pretty funny.
