Michael Phelps or Mark Spitz: Who Would You Rather ...

Earlier today, we published reports that Michael Phelps might be dating fellow Olympic swimmer Amanda Beard. Or British model Lily Donaldson.

Heck, he could be dating both of these beauties and he'd still need to add six girlfriends in order to match his gold medal haul from Beijing last week.

Truly amazing stuff. The only man even close to equaling Phelps' accomplishments in the water is Mark Spitz, who took home seven golds in 1972. Still, it's unlikely Spitz could defeat his Olympic counterpart in a head-to-head race.

But can he defeat him in a match-up of who could bed the most babes?

Take a look at each of these swimmers shirtless and let us know who you'd rather, well, you know ...
