"Shake a leg," huh? Reminds me of the revenge I got with one of my workers...he had plastered a local band's bumper stickers on the ceiling fans, and my car's bumper and side panel, in a place I used to work. So to get even with him, I poured jalapeno juice into his coke... The poor kid would've been in a world of hurt, but I had gotten an ice water when I saw him moving toward his coke, so while he was downing the quart of i/w, I told him, "Listen and listen good: Don't bring those bumper stickers around anymore, and DO NOT even think about trying to beat me at pranks." To which he readily gave in.
