Swimmer, Michael Phelps, has basically dominated every human he's every competed against...so now he's taking on another species.
Apparently he'll be racing a Great White Shark in segment for Discovery Channel's "Shark Week." There's no word if they'll be swimming side-by-side or even at the same time; but if you're interested, it will air on July 23rd (which is the first day of "Shark Week").
