Ouch! Hopefully that won't happen to my daughter, she's so tiny. The only wii mishap we had was when we didn't have the wrist strap for her controller and she was playing bowling and the remote went flying straight up... Forunately no one or nothing was injured... needless to say we bought a strap for her controller the next week.
