guy with crutches on tosh.o

Saw an episode of tosh.o tonight (the one with the "smell your dick" web redemption) and at the beginning of it there's a guy in metal crutches with some kind of metal bar attached to his groin. He proceeds to cross a stage to a pullup bar, and starts making humping motions so that the metal bar hits the pullup bar.
I feel like a failure cause I can't find and clips from season 4, episode 11, but I immediately thought someone on the fark board could work their magic and create the best gif known to man.
