Last night marked Jay Leno's triumphant return to The Tonight Show, and guest Jamie Foxx could not have been more excited. It's safe to say Foxx wasn't a member of Team CoCo — he celebrated like he'd just toppled that statue of Saddam Hussein in Baghdad. Spirits also ran high on Jimmy Kimmel Live, where the host managed to cure a major case of Bieber fever in a 3-year-old fan who cried about her love for the singer on YouTube. In other screaming-girl news, Jimmy Fallon trotted out one of his "Robert Is Bothered" sketches, which feature a brooding Robert Pattinson in a tree, only to find his usual tree occupied by a brooding Robert Pattinson. Finally, Bill Murray stopped by The Late Show to explain how he found himself singing the Ghostbusters theme one Sunday in Manhattan, while Don Cheadle's new role as an undercover cop made Stephen Colbert instantly suspicious. A side note: Murray didn't give a real explanation for his figure-skating top. Watch our compilation to see what you missed.
