Michael Phelps Vegas Retirement Party

 When most people retire, they get a few cards poking fun at how old they are and a cake. But not for Michael Phelps ... Vegas baby! 

This world record breaking Olympic swimmer started off this week by throwing it down in the great Las Vegas and reportedly won $100,000 playing poker. This was only the beginning of his early retirement from competitive swimming.
