Hahaha...I remember that game...that is like Rambo looking character in the game right? BTW, the FB is cool!
I can't remember what that's from, but it use to be a cheat code for an old game on the NES or SNES system.. Something like infinity lives or something in a really old game. Pretty funny they would put something like that into FB. I would guess it's some kind of java code. It crashed Firefox on my machine after about 10 seconds, but it was pretty funny to see.
