Wii injury

No, that's not a typo. I do not have a wee belt...err...injury. I have a Wii injury. I played Naruto after much protest Saturday night and now my arm hurts. It didn't hurt yesterday while I lazed around the house, but today it does. Must be all the typing and whatnot. Owie. It's quite sad. I feel like I should maybe go to the gym. O.o
