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.

The 2015 late-night talk shows are now in session! "The Tonight Show" welcomed the new year with Bradley Cooper playing Neil Young's "Down by the River" on air guitar while wearing a crazy birthday hat afro and thrusting his crotch in audience members's faces. It's going to be a good year.

The story behind the crazy afro hats is that Jimmy gave one to Bradley for his birthday (Bradley turned 40 on January 5), then rocked one himself. Bradley also talked about Clint Eastwood and "American Sniper," which sounds like a strange transition, especially since they did so much laughing. They just got a case of the giggles and couldn't let it go.

ABC's new Bachelor, Chris Soules, was on "Jimmy Kimmel Live," talking about Monday night's premiere. Does he like being called Prince Farming? Does he get to keep the clothes? Has he been back to farming? Jimmy said he knows who wins this time because he invaded Chris's inner sanctum. (He probably always knows who wins from spoilers, but he's refraining from sharing his "prediction" this time.) Jimmy shared a bunch of contestant photos, and Chris reacted with "crazy or not crazy." Jimmy laughed and stopped him at one point, since Chris was giving away too much real information. Jimmy said he might get sued by ABC from all of Chris's spoilery answers.

Anne Hathaway was also on JKL, and Jimmy asked her if she watched "The Bachelor." She said no, but she does watch some reality TV. Or she did, for one day, when she had swine flu. She binge-watched "Toddlers & Tiaras." Ha! She also talked about spending the holidays with her family, and she and Jimmy discussed the cut-off date for "Happy New Year."

Kathy Griffin was on "Late Show" and she called the Fashion Police on David Letterman, to declare him one of the worst dressed. You can imagine how deeply Dave cared. #sarcasm They posed together, though, and Dave said she looked great. He said he's not supposed to look great. Kathy disagreed. She also discussed her pre-telecast dinner with Ryan Seacrest and Anderson Cooper (she bashed the heck out of Ryan, you almost have to feel sorry for the guy) and talked about dyeing Anderson's hair live on TV. She and Dave also shared some interesting sexual innuendo. "Selma" star David Oyelowo was also on Dave's show, talking about theater, spoiling his kids, and his role as MLK Jr. Very different from Kathy Griffin.

Anna Kendrick, always the best part of any talk show, was on "Late Night" with Seth Meyers, and she talked about singing in "Into the Woods" and preparing for "Pitch Perfect 2." Apparently the Green Bay Packers are huge PP fans and they're in the sequel. Anna also talked about how much she loves red pandas. She went to the zoo on Christmas day and saw the pandas. Now she wants a whole farm of them.

Donald Faison was on "Conan," talking about the difference - to him - between "Star Wars" and "Star Trek." He likes one much more than the other. Much. In fact, he dogs the other one as boring and lame.

Courteney Cox was also on "Conan," and apparently she has a really bad memory. She produces a show called "Celebrity Name Game," hosted by Craig Ferguson (miss you, man) and she talked about the pressure of the game and her lousy memory. They showed a clip where she just couldn't come up with '80s band intel. It's tragic. She said her memory is so bad that she forgets when she doesn't like someone. She also talked about passing up a Central Perk pop-up store.
