Cubs left-fielder Moises Alou hit .400 this week with 3 home runs and 4 RBIs. How did he do it? Peeing on his hands to harden them may have helped. Apparently he's not alone in the practice. But Slate points out that urea is a common ingredient in skin moisturizers, and the fact that Alou has only 8 errors in his Cub career suggests very soft hands indeed.
