A duck walks into a store and asks the cashier, “Do you have any grapes?” The cashier replies, “No, sorry, we don’t have any grapes.” The duck leaves, but comes back the next day and asks the same question. The cashier, now a bit irritated, replies, “I told you yesterday, we don’t have any grapes.”
The duck keeps returning day after day, asking the same question. Eventually, the cashier loses his patience and yells, “I’ve told you a hundred times, we don’t have any grapes! If you come back asking for grapes again, I’ll nail your beak to the floor!”
The next day, the duck returns and asks, “Do you have any nails?” The cashier, confused, replies, “No, we don’t have any nails.” The duck then smirks and asks, “Do you have any grapes?”
