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.

Steve Carell kicks off the late night roundup with a game of Word Sneak with Jimmy Fallon, in which you get a series of words and try to insert them into the conversation as seamlessly as possible. Some of the wordy highlights? "Pantaloons," "fluffernutter," and of course "Anderson Cooper."


Julianna Hough also made an appearance on "The Tonight Show" and promptly helped Jimmy find a signature dance move. Let's just say he won't be asked to compete on "Dancing with the Stars" anytime soon....


Elle Fanning showed up on "The Late Show" to show off her brand new brunette locks to David Letterman, which took seven hours to dye for a new movie. Blonde have more fun, but Elle looks –– as David Letterman and Tony The Tiger say –– grrreat!


Emmy Rossum moseyed on by "Late Night," and shared the story of how she filled her car up with gasoline...using a champagne flute to do so. File this one under #hollywoodproblems.


Last, but definitely not least, LL Cool J told Jimmy Kimmel about the time he was arrested for humping a couch in Georgia. Jimmy's reaction? "Miley Cyrus would probably get the death penalty in that town."
