The good folks over at Mens Fitness put together a list of the top 10 most superstitious athletes. Who knew that eating chicken, wearing skimpy lingerie, and drinking your own urine could ensure a high level of play?

Michael Jordan

You wouldn’t think the greatest professional basketball player of all time would rely on superstition, but even Michael Jordan himself was known for a specific quirk. While leading the Chicago Bulls to six NBA championships during his legendary career, the five-time MVP wore his University of North Carolina shorts under his uniform in every game. Jordan led UNC to the NCAA Championships in 1982 and believed the mesh marvels brought him luck. In order to cover his lucky pair, Jordan began wearing longer shorts, which inspired a trend in the NBA.

Lyoto Machida

It’s unclear whether UFC Light Heavyweight Champion Lyoto Machida’s daily habit is a form of superstition or self-torture, but every morning the Brazilian Shotokan karate master drinks his own urine. Revealing that he picked up the practice from his father, himself a karate master, the 31-year-old Brazilian has said he believes urine is a natural medicine that cleanses his body. While it sounds disgusting, Machida may be onto something—The Dragon has yet to lose a round in his professional mixed martial arts career.
