Have them fight each other.

Live (to tape) from Union Square: Hipster Fight Club. "A number of shirtless, scraped-up men paced the perimeter of the circle, alternately refereeing and answering questions. The rules were simple: find a partner, get in the ring. No face shots, tapping out ends the fight. No settling scores, just fighting for the fun of fighting. No experience or discernible skill required. A couple of emo-hipsters in matching floppy sideways haircuts and matching white belts got into the act, proving that one does not inherit martial arts skill by simply being Asian." [AIANL]
