A couple went to a pet shop and ended up buying a lion (as you do). The shop owner had told them that unfortunately the lion had an odd allergy to wet weather and that raindrops would actually hurt it.
One day the lion was outside when the couple heard cries form the garden. "What's that noise?" asked the man. "It's the lion", his wife replied, "it's roaring with pain."
