A rabbit goes into a shop and asks, “got any carrots?” The shop keeper says no and the rabbit leaves. The next day, the rabbit returns and asks, “got any carrots?” Once again the shop keeper says no and the rabbit leaves.
This continues for a week. The next day when the rabbit enters and asks for carrots the shop keeper says, “no! And if you come in here asking for carrots I’m going to nail your ears to the wall.”
The next day the rabbit comes in and asks, “got any nails?”
“No,” says the shopkeeper.
“Good,” says the rabbit. “Got any carrots…?”
