Michael Phelps -- Cereal Killer

Five out of five dentists say Michael Phelps is all wet -- when it comes to his choice of breakfast cereal.

Health experts are going nuts because Mikey likes Frosted Flakes, and is going to be on the FF box rather than a Wheaties box, like pretty much every other big-shot athlete. They're all up in arms because Flakes has three times as much sugar as Wheaties and only a fraction of the fiber. Not so grrrrrreat after all?!

We've put in a call to the Wheaties peeps, but haven't heard back yet.
