When the ark's door was closed, Noah called a meeting with all the animals and said in a demanding voice:
"Listen up kids! There will be NO sex on this trip. Not even the wetting of the tip of your penis. All of you males, take off your penises and hand them to Jim the Monkey. He will write you a receipt. After we see land, you can get your penis back."
After about a week, Mr. Rabbit ran over to his wife and very excitedly said, "Quick! Get on my shoulders and look out the window to see if there is any land out there!"
Mrs. Rabbit got onto his shoulders, looked out the window and said, "Sorry, no land yet."
"S**t!" shouted Mr. Rabbit and out he went.
This went on every day until Mrs. Rabbit got fed up with him.
"What is the matter with you? You know it will rain for forty days and nights. Only after the water had drained will we be able to see land. But why are you acting so excited every day?"
"Look!" said Mr. Rabbit with an impatient look on his face as he held out a piece of paper. "I GOT THE DONKEY'S RECEIPT!"
