Please pull up your pants. I don't know if you're aware, but you've been sporting a little bit of a plumber's crack for most of the Olympic games and I think you really need to address this fact. If not for the sake of decency (mooning a multinational TV audience is probably not all that diplomatic), perhaps for the sake of performance. In a sport where leg hair produces too much drag, I can only wonder how many precious milliseconds are lost to the drag created by water rushing into your exposed butt crack... So please, for the sake of your teammates and the world audience, pull up your pants.
