AC vs Phelps: The 2012 rematch

Four years ago, Anderson Cooper challenged Olympic champion Michael Phelps to a one-lap race. Anyone want to guess how that went? (Imagine competing against a dolphin.)

Even with a significant handicap -- Phelps wasn't allowed to dive in, take strokes, or breathe -- the swimming phenom easily swept past our brave correspondent.

In May, they meet again for a rematch (oh, and also for a 60 Minutes story about Phelps' preparationfor the summer Olympics in London...but enough about that.) This time, The Olympian and The TV Reporter faced off on dry land, where Mr. Phelps lost some degree of advantage.

As you'll see, Anderson takes an early lead. Then things get interesting. Can Anderson Cooper finally win one for Team 60 Minutes?
