So this duck walks into a bar, jumps up on the bar and asks the bartender, "Hey man, you got any duck food?" The bartender looks at the duck and says "No, this is a bar and we ain't got no duck food. Now get out of here!" The duck says "Alright, alright I'm going." The next night the duck walks back into the bar, jumps on the bar and asks the bartender, "Hey man, you got any duck food?" The bartender looks at the duck and says, "I told you last night, this is a bar and we ain't got no duck food. Now scram and if you come back in here again asking for duck food, I'm gonna nail your feet to the bar!" The duck says, "ok, ok, I'm going." The next night the duck walks back into the bar, jumps up on the bar and asks the bartender, "Hey man, you got any nails?" The bartender says "No." The duck says, "Good, you got any duck food?"
