Donkey's receipt

This is one of my favorite jokes....I cleaned it up a bit though to make it a bit more clean :)

When the ark's door was closed, Noah called a meeting with all the animals.
"Listen up!" Noah said with a demanding voice. "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 it in with my son's. I will be sitting over there and write you a receipt. After we see land, you can get your penises back."

After about a week Mr. Rabbit stormed into his wife's cage and was very excited. "Quick!" he said. "Get on my shoulders and look out the window to see if there is any land out there!" Mrs. Rabbit got onto his shoulders and looked out the window."Sorry, no land yet." "Darn!" and out went Mr. Rabbit.

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 a sinister look on his face as he held out a piece of paper. "I got the donkey's receipt!!"
