A cat and a rooster die but end up in the wrong heavens. The cat is in rooster heaven and the rooster is in cat heaven. There is a river between the two heavens and they both must cross it to get to their rightful place.
The rooster flies over to his heaven without a hitch, but when the cat tries to cross over, he falls in and gets totally wet.
What's the moral of the story? When there's a happy cock, there's a wet pussy.
