What does it feel like to race Michael Phelps? Anderson Cooper can't tell you because even though he took to the pool with the Olympic swimmer, the dolphin-moving Phelps blew right by the journalist. If there is such a thing as dust in a swimming pool, Cooper was left in it.

Cooper told Kelly Ripa on Friday's Live with Regis and Kelly that Phelps claims he is currently not in very good shape. A perfect time to challenge him in the water, then, thought Cooper, who gave the swimming great a few conditions -- Cooper could swim as usual, but Phelps had to swim under water and wasn't permitted to breathe or use his hands.

This video shows quite a spectacle -- and I'm not just talking about Cooper's display of swimwear, which he happens to admit is not near as sexy as the suit sported by Phelps. Ripa expects a Speedo for the next swim-off.

So much for fashion. Let the contest begin.
