Dance Central and You Don't Know Jack demos on Xbox Marketplace

Body and mind. Mind and body. For all the Dance Central haters who've never actually played the game, the Xbox Marketplace has a demo available now to test out the hit title. Your body will thank you ... or cause you to retch from the exercise of a three minute dance routine.

As for your mind, beware the barbs of You Don't Know Jack emcee Cookie Masterson. The crazy quiz show also has a demo available today. And remember: Never give up, never surrender until the Jack Attack is over.
