If you’re claustrophobic then Jimmy Fallon’s new Tonight Show segment may not be for you. On Friday night, Fallon and House of Cards star Kevin Spacey played “Phone Booth,” a trivia game played inside a pair of phone booths. If the contestant answers incorrectly – or their opponent gets a question right – another person is added to the opposing player’s booth.

Needless to say, things didn’t go well for Spacey at first. The initial few rounds found Keegan-Michael Key from Key and Peele, 6-foot-11 NBA Draft pick Karl-Anthony Towns, and actress Mae Whitman turning Spacey’s booth into a glass case of emotion. Said Spacey upon answering the phone to play in a later round: “Yes, most ridiculous sketch ever.”

But fortunately, the tide turned – and not a moment too soon, since Fallon even had Big Bird waiting in the wings to join the fun.
