Olympic gold medalist Ricky Berens had to swim with his ass exposed to the World Championships audience after the back of his suit split. He was swimming the 4×100 freestyle relay, bent over to stretch, and ripped his suit wide open seconds before his turn to swim. Berens was also a gold medalist in the same event last year in Beijing. Luckily, he put his head down and the US still qualified for finals (and won the event).
