Keri Russell stopped by "The Tonight Show" on Tuesday, where she took on Jimmy Fallon in a game of "Inflatable Flip Cup."
"The game is simple," the late night host explained. "We each have six cups, first to chug the beer and flip all of their six cups upside down, wins. We're doing all of this in these inflatable suits. These are great!"
The best part? Before they started the game, Keri and Jimmy showed off their best dance moves in their matching puffed-up suits!
Even though she was new to the game, the "Felicity" alum held her own and gave the comedian tough battle. Check out the clip above to see who came out on top!
