Los Angeles Angels outfielder Vladimir Guerrero has an inherited condition that makes him run in circles counterclockwise. Fortunately, he found a job that pays him for doing this.
"I have a family history where there is one leg proven that is longer than the other," Guerrero said, adding that it's the right one in his case. "So when I hobble, it's not my knee. My mom's side of the family, we have a leg longer than the other. So it looks like I'm hobbling, but I'm not. But my knee is fine." [Link]
