A woman goes to buy a large cactus from a nursery, and brings it home. Later that day she notices something very odd. The cactus appears to be breathing! She calls the nursery she purchased the cactus from and says, "I know this sounds crazy, but I think my cactus is breathing."
The woman she is speaking to tells her to immediately get out of the house, and that she (the nursery woman) is going to call the bomb squad. The bomb squad comes to the house and loads the cactus into a van. Just as they get it into the van, the cactus explodes and out come thousands of scorpions!
It seems that several scorpions had laid their eggs in the cactus, and they all hatched at once.
