There is an adage in showbiz that a bad dress rehearsal means a good performance.
It certainly seemed to be true for Chloe Kim, who dropped to her knees after her first, and ultimately gold-medal-winning, run of the Olympic halfpipe final and said, "I had the worst practice of my life!"
She scored a huge 94 in that run, twice soaring more than 12 feet over the rim of the superpipe in Beijing. None of her competitors could match her score (or her height) in any of their three runs. Queralt Castellet of Spain won the silver with a 90.
