"Tonight Show" takes some hair off trivia contestant's chest

On a night where Jimmy Fallon's guests ranged from Barbara Walters to Honey Boo Boo, why not include some chest waxing?

Two friends from Philadelphia played the show's "Wax On Wax Off" trivia game, where one contestant has hair waxed off his chest for every question his friend gets wrong.

It's a painful watch, but good for a few laughs.

Speaking of laughs, in a web exclusive, comedienne Iliza Shlesinger, also a guest on Wednesday's show, shares a story of the worst time she's bombed on stage.
