Wii health precautions

I don't know if you've seen any of the reports for the dangers of using a Wii. Since people are flailing those controllers around like berserkers, there have been black eyes, broken bones, damaged windows, etc. We're pretty careful to remember to use the strap for the protection of ourselves and those around us. Well, this weekend, a friend came over to check out our new game system and while we were playing baseball, we discovered another danger of the Wii. Margaret was sitting down watching us play. I was pitching and our friend was at bat. (I'm deliberately keeping the description neutral, as it would be easy to guess who it was if I even gave a clue as to the gender of said friend.) Anyway, our friend was standing in front of Margaret, back towards her. When the ball was pitched and our friend swung the controller, a loud fart escaped right in Margaret's face. I fell over laughing and couldn't pitch anymore, and Margaret was left wondering whether it was better to be hit in the face with a Wii controller or a cloud of noxious gas. There's one more thing that Nintendo needs to add to their list of warnings.
