A duck walks into a bar and asks the bartender if he has any grapes.

Needless to say, the bartender is rather surprised at this. Not only is there a talking duck, but he wants some grapes. Rather annoyed at how odd this is, he gruffly says "no grapes". The duck leaves.

The next day, the same duck walks in again and asks "do you have any grapes?".

Knowing he had answered the same question to the same darn duck the day before, the bartender responds "I told yeh yesterday, no grapes!" The duck leaves again.

The following day, the same duck walks in for a THIRD time, going up to the bartender and asking "do you have any grapes?"

Now this bartender has had enough of this duck goofing around asking people for grapes and just being too odd to deal with. "IF YOU COME IN HERE ASKING FOR GRAPES ONE MORE TIME, I'M GOING TO NAIL YOUR DUCK FEET TO THE BAR!" yells the bartender. The duck quietly leaves, and the bartender wipes his forehead hoping that he won't see the duck again.

Much to his dismay, the duck does in fact come back the next day. Instead of the usual however, he asks "got any nails?"
