Arnold Schwarzenegger is auctioning off chances for someone to fly to Los Angeles, hang out with him for a day and crush stuff in his TANK.  All the proceeds benefit the children's charity After-School All-Stars.  

You enter the contest by donating a minimum of $10 to a charity called After-School All-Stars. (Here's where you can enter.) The 10 bucks gets you one entry, but you can enter as much as you want.

Arnold even made an AWESOME video hyping this chaos.  And if, after watching it, you aren't DYING to crush stuff with Arnold, you seriously need to have your testosterone levels checked.
