VIDEO : Jimmy Fallon and Ricky Gervais Get the Giggles During Their 'Funny Face Off'

The hilarious Ricky Gervais stopped by The Tonight Show Starring Jimmy Fallon on Friday night, and thankfully, he was down for a few rounds of "Funny Face Off." Both Jimmy and Rickey had trouble keep it together as they tried to imitate the funny faces sent in by young fans. It's all fine and good, though, because Ricky has one of the best celebrity laughs in Hollywood.??
