They wear inflatable suits to face off against each other.

Keri Russell has never played flip cup before. (As Felicity, she was too busy studying and thinking about her love triangle apparently.)

Russell and Jimmy Fallon wore inflatable suits for the drinking game on The Tonight Show on Tuesday. First, they had themselves a nice little dance session to pump up in preparation. Then they got down to the business of chugging and flipping, until it all got a little overwhelming for Russell.
