What do you do after winning 28 Olympic medals? Race a great white shark, that's what.

The Discovery Channel will kick off the full week of shark-related shows on July 23rd with "Phelps vs. Shark: Great Gold vs. Great White", I guess being the most decorated Olympian of all time isn't enough for Michael Phelps.

With a great white reaching speeds of up to 25 mph and Michael's swimming speed at about 6 mph during the 2010 Olympics, sorry Phelps, but my money is on the shark.

Not to mention that great whites can launch themselves 10 ft in the air. Oh, and those teeth. Let's not forget about their 300 teeth. Hopefully the "Great Gold" and the "Great White" are in lanes separated by a very think and very high barricade.

How do you get a shark to race, anyway? I guess we'll all find out on July 23rd!
