Want to see the best exploit of 2012 (so far?) Look no further than new MMO Star Wars: Old Republic, which literally lets you dance your way out of trouble.
If you're being attacked by anything, from the lowliest enemy to the grandest boss, all you need to do is start dancing - triggered by typing /getdown - and it'll interrupt their attacks, leaving you invulnerable.
Game-breaking. And hilarious.
