>>1739038A duck walks into a bar, walks up to the bartender and asks, "hey barkeep, got any grapes?" The bartender says "no, we don't have any grapes" and the duck walks out. The duck comes back an hour later and walks up to the bar, "hey barkeep, got any grapes?" The bartender once again says, "no, we don't have any grapes!" The duck walks out again. After another hour the duck comes back and the bartender says to him, "if you ask me if we have any grapes, I swear I'm going to nail your beak to the bar." The duck asks, "Hey, you got any nails?" The bartender says, "no" and the duck replies, "hey barkeep, you got any grapes?"
