So you're walking down the street, PSP in hand, when you're suddenly attacked by rabid werewolves who tear your top to shreds and disappear just as quickly.

What do you do?

If you're one of the lucky people who live somewhere near an upcoming PlayStation Experience or PlayStation Locker Room Challenge Tour event, you could just show them your PSP.

Sony is giving away brand-spanking-new T-shirts to lucky participants of their promo tours. All you have to do is show them your PSP and pray they still have stock, and you've just replaced your tattered rags with a PlayStation Portable shirt. The promo runs from now up to October 29, so you may just find yourself in-luck.

Here are the schedules if you're interested, though they're subject to change. Check the source for updates and schedule changes as they occur:
