I never did understand this saying. When my daughter was in school, she played softball and she's a 'lefty'. My friend's husband from down the street wandered by and he was talking to my daughter about the advantages of being a left handed pitcher. He was telling her about the different pitches, etc. and at one point he said "If you throw a pitch like that the batter won't know whether to s**t or go blind. I must have gotten a funny look on my face as I pondered those two choices. He thought I was mad that he said the "s" word to my daughter and apologized. I told him it was okay to say that word but what the heck kind of choice is s**t or go blind? I mean, really, who would rather go blind than s**t?
