The Wii is a bad creation. It hurts. Tennis, bowling, baseball, gold and Guitar Hero. My arm hurts. My almost brother-in-law brought his Wii to Christmas at my parents, and we played. A lot. Ouch.
In a related story, in between runs at my parents' house, I did nothing but eat, drink and sit around. I am wicked tight, and my right knee doesn't feel very good. I think I'm going to take a couple days off and just stretch.
