I went to the Sunday game of the Cubs-Twins series in June, and I was sitting in front of a random lady who was trying to teach her kids stuff about the game, and I could tell she thought she knew a lot about it. Then one of her kids asked her what the "K" signs they were putting up meant. She knew it meant strikeout and said as much. Then the kid asked why some were backwards, and her response was that they don't want to put up KKK, so they switch one around as to not offend anyone. She was dead serious, and I chuckled to myself.
