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 time has come for a game of Slap Jack with Mark Wahlberg and Jimmy Fallon! Basically, it's like Blackjack –– only at the end of each round the winner gets to slap the loser with a giant prosthetic hand. And yes, it took Marky Mark less than two minutes to make a crack about Ben Affleck counting cards. Fair enough.

So, Jimmy Fallon and Steve Carell have formed a Barbershop Quartet called The Rag Time Gals and it's completely amazing. Much like their performance of Marvin Gaye's "Sexual Healing." You're welcome, world!

Cameron Diaz stopped by "Late Night" to chat about her upcoming role in "Annie," and apparently her favorite part of the experience was being able to yell at kids "without getting arrested." We all have our quirks, Cameron.

Apparently Hollywood's resident award-winner Meryl Streep recently won the Presidential Medal of Freedom, and naturally POTUS bestowed the honor upon her himself. Turns out he's just as big of a fan-boy as the rest of us. Check out Meryl tell the story to David Letterman on "Late Show"!
