Team USA just won gold in the relay making history for Michael Phelps with 8 gold metals in a single Olympic Games. Phelps beat Mark Spitz record by one.

That makes a total of 16 Olympic gold metals for Michael Phelps.

Jason Lezak helped Phelps make history as his teammate in both relays.

Phelps tied the record Saturday by beating Serbia's Milorad Cavic by the slimmest margin in swimming history -.01 seconds - in the 100-meter butterfly.

Doesn't Michael Phelps just make you proud to be an American?!
