Being Jimmy Fallon’s Guest Looks Like So Much Fun! [VIDEO]

Celebrities must line up to be a guest on 'The Tonight Show With Jimmy Fallon' because it's so much fun! Guests don't just sit and talk about their latest project. Instead, they lip sync or play fun games, like on Keri Russell's first visit in an inflated suit!

Jimmy convinces Keri to play 'Inflatable Flip Cup' and she's a really good sport about it. The suits are hilarious, even without the attempts to drink from plastic cups and then flip them over. Flipping them proves very challenging with the limitations of the suit.

Keri does pretty well at first. But when she starts to fall behind, one of her cups ends up 'accidentally' smacking Jimmy. Funny, funny stuff!
