They keep rolling in. Thanks to a Crave tipster, we found this hilarious YouTube video by user "RobotsPiratesNinjas." Set to Queen's "We Will Rock You," the clip details the antics of a group of teenage boys who claim to have accidentally smashed a light fixture in a Wii Sports tennis overhand serve. Even if they're exaggerating, it's still a pretty funny video. Especially with that soundtrack.
Additionally, Kotaku has posted a link to Nintendo's official safety precautions regarding the Wiimote and its tendency to fly out of players' hands and smack into stuff like TVs, lamps, and cats. My favorite line: "If you are having so much fun that you start perspiring, take a moment to dry your hands."
Wii will, wii will.
