"Putz: literally, a diminutive form of penis; a prick. Used, as we do in English to describe a nasty, unlikable man. A putz generally has no real power, except to make your life miserable or at least unpleasant, often in a passive-aggressive way. See also Shmuck."
As I see it either way the Mets' J.J Putz is going to get teased this year in NY. It's a Yiddish town. If he wins for the Mets then we get a lot of headlines that we chuckle over and his opponents will think he is a putz, and if he has a bad season we'll will think he is a shmuck. Is there a joke to be made about a double header?
