Animal Heaven
A cat and a chicken die but end up in the wrong heavens. The cat is in chicken heaven and the chicken 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 chicken flies on 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.
