A duck walked into a store and asked, “You got any grapes?” The store clerk said, “I’m sorry, but we don’t have any grapes.” The duck leaves. The duck comes back the next day and asks, “you got any grapes?” The store clerk said, “No, I already told you, we DON ’T carry grapes.” The duck leaves. The duck comes back the next day and asks, “You got any grapes?” The store clerk yells, “NO! We do NOT have ANY grapes! If you ask one more time I’m going to nail your feet to the floor!” The duck leaves. He came back the next day. “You got any nails.” The clerk replied, “No we don’t have any nails.” And the duck says, “You got any grapes?”
