A duck walks into a bar and asks the bartender if he has any
grapes.The bartender replies no, and the duck leaves. The very
next day the duck returns, and again asks if the bartender has
any grapes. Again the bartender replies no, and the duck leaves.

The next day the duck returns, and asks for grapes. The
bartender, understandably is a little miffed, so he says to the
duck, "listen buddy, I have told you, I didnt have any grapes
the day before yesterday,I didnt have any grapes yesterday, and
I have no grapes today! If you come in here asking for grapes
again, Ill nail your feet to the floor!" So the duck leaves.






The next day the duck returns,and askes the bartender if hes
got any nails? The bartender says no. The duck asks........Got
any grapes?
