A duck walked into a bar, hopped onto the bar and asked the bartender, "Do you have any grapes?" The bartender replied, "This is a bar, we serve drinks, not grapes." The duck shrugged it's wings and walked out. The next day, the same duck walked into the same bar, hopped up on the bar and asked the same bartender, "Do you have any grapes?" The bartender replied, "This is bar. We serve drinks, not grapes. I told you that yesterday." The duck shrugged it's wings and walked out. The next day, the same duck walked into the same bar, hopped up on the bar and asked the same bartender, "Do you have any grapes?" The bartender, visibly upset, says, "I told you yesterday, duck, this is a bar. We serve drinks, not grapes. If you come in here again, I will nail your feet to the bar." The duck shrugged it's wings and walked out. The next day, the same duck walked into the same bar, hopped up on the bar and asked the same bartender, "Do you have any nails?" to which the bartender said, "No". The duck said "Got any grapes?"
