The Duck Song Joke

A duck walks into a store and goes up to the storekeeper.

Duck: "Do you have any bread?" Storekeeper: "No." Duck: "Do you have any bread?" Storekeeper: "No." Duck: "Do you have any bread?" Storekeeper: "No." Duck: "Do you have any bread?" Storekeeper: "If you ask me one more time if I have any bread, I'm going to nail your feet to the floor!" Duck: "Do you have any nails?" Storekeeper: "No." Duck: "Do you have any bread?"
