Having held the world record in the 100-meter dash years ago, Maurice Greene was considered the fastest man alive.
This season on Dancing with the Stars, we'll find out if speed kills his chances... or dooms his opponents. Greene's partner will be Cheryl Burke.
"I told Cheryl I hope I don't make you mad by calling you up in the middle of the night and saying, 'Let's go work out!' Green said. "I've already texted her twice before and she says, 'You're crazy! Take your time.'"
