A duck walks into a 7-11, goes up to the counter and asks the cashier, "You got any grapes?" The cashier responds that they have no grapes and the duck leaves.
The next day the same duck walks in and asks again, "You got any grapes?" The cashier, a bit annoyed, tells him that they still have no grapes. The duck leaves.
The very next day the same duck walks in and once again asks if they have any grapes. This time the cashier angrily responds, "Look, we don't have any damn grapes. If you come in here one more time asking for grapes I'm gonna nail your stupid webbed feet to the floor." The duck quietly exits.
The very next day the same duck walks in, approaches the counter and asks the cashier, "You got any nails?" The cashier says "No." The duck responds, "Good, you got any grapes?"
