A duck walks into a pet store and asks the attendant, "Do you have any duck food?" The attendant says "No" and the duck leaves. The next day the duck is back and enquires once more, "Do you have any duck food?" The attendant, thinking the duck very stupid, replies, "No." The duck exits the store. He repeats this process again and again.
Several days later the duck returns to the pet store. This time he receives the answer, "No, and the next time you ask me if we have duck food I'll nail your feet to the counter and bash your head in with a cricket bat." The duck smiles complacently and leaves.
The duck strolls into the store the next day, moseys up to the counter and asks, "Do you have any nails?" Put slightly off his guard, the attendant mutters, "No..." So the duck grins and asks, "Do you have any duck food?"
