Here's a little story for y'all. Sometimes large cactus are harvested from the wild. Probably not legal, but the cactus found it's way into someone's home. They thought they heard noises, they thought they saw the cactus shake. Yes, they heard noise, yes they say it shake. It was home to a zillion scorpions that quickly filled the house. True or not, dunno. Always liked that story though.....
