Guy I work with loves to play pranks on customers. He made a big round circle out of card board then tape about 12 inches to the card board and rolled it around. He took out the toilet paper from the mens room out and stuck that in place instead. he also wrote dont you wish you looked before you sh!t? that Read at the end of the tissue when full pulled. He took out the paper towels as well but he said he put a can of Lysol in there... crazy
