A rabbit enters a bar and orders, "One beer, you jackass."
The baker gives him what he wants without saying anything.
Next day the rabbit comes again. "One beer, you jackass."
This time the baker says (after giving him his beer),
"Just call me a jackass once more and I will take two nails and nail
your ears on the door."
Next day the rabbit comes again into the bakery and asks, "Do you have nails?"
"No", says the baker.
"Then give me one beer, you jackass!"
