Twenty-three-year-old Tanner Hall owns freestyle skiing, but he lets other guys play to keep things interesting. The Park City, Utah, native has won five gold medals at the Winter X Games and has called downhill racing ?easy.? Not easy? Tanner?s attempts to push the limits of physics. In thiz 2005 clip, boyfriend busts himself up pretty badly when he attempts a ?switch 900? (two consecutive mid-air spins off a 120-foot cliff). The sights and sounds must be seen to be believed. Don?t plan to sleep tonight.
