After getting trapped in the ant lion's den that is Think Geek, lured in by seemingly inoncuous Mario blocks, I fought my way out with this little treasure. It's Pong! The shirt! Just as the gods intended! The paddles and ball really move, running of three fashionably hidden AAA batteries (batteries not included). This with a Pong watch and Space Invader cufflinks and you've got the uber-gamer outfit!
Sadly, though, you can't actually play the game dancing on your chest, but it's a step in the right direction. Call me when I can look down and use my belt buckle to stomp goombas.
