How The Cast Of 'This Is Our Youth' Got Tavi Gevinson To Talk About 'Some Of Hitler's Concepts'

The cast of "This Is Our Youth" certainly knows how to keep things interesting.

Michael Cera, Tavi Gevinson and Keiran Culkin invented a risky game to play secretly during interviews about their hit Broadway play, they told HuffPost Live's Ricky Camilleri on Tuesday. The idea is simple: the group comes up with an outlandish or inappropriate phrase, and the cast member who works it into casual conversation wins anywhere from $5 to $20.

The winner so far is Gevinson, who managed to say "some of Hitler's concepts" during a discussion about the play (see it at 2:50 in this video).

Watch the cast chat about the game and some other phrases they've considered playing with in the video above, and see the full HuffPost Live conversation here.
