Given that I've posted periodically about various forms of urine therapy, I was intrigued to come across this slate.com article alleging that many professional baseball players regularly pee on their hands in the belief that the urine will toughen their skin:

"In a recent interview with ESPN's Gary Miller, Chicago Cubs outfielder Moises Alou revealed that during baseball season he urinates on his hands to toughen them up. Alou, one of the few major leaguers who doesn't wear gloves while batting, is backed up by Yankees catcher Jorge Posada, who says, "You don't want to shake my hand during spring training." Even Cubs hurler Kerry Wood mentioned on a local radio show that he's tried the technique to remedy blisters on his pitching hand."

The article goes on to argue that urine probably would work well to soften your skin since urea is an ingredient in many commercial moisturizing lotions, but it's very doubtful that it will do anything to toughen up the skin. Slate.com figures that this hand-peeing fad is just another one of the many superstitions that baseball players get hooked on to try to improve their game.
