“A ducks walks into a bar and asks, â€œGot any grapes?â€
The bartender, confused, tells the ducks that no, his bar doesnâ€™t serve grapes. The duck thanks him and leaves.
The next day, the duck returns and says, â€œGot any grapes?â€
Again, the bartender tells him that, no, the bar does not serve grapes, has never served grapes, and, furthermore, will never serve grapes. The duck, a little ruffled, thanks him and leaves.
The next day, the duck returns, but before he can say anything, the bartender begins to yell:
â€Listen, duck! This is a bar! We do not serve grapes! If you ever ask for grapes again, I will nail your stupid duck beak to the bar!â€
The duck is silent for a moment, and then asks, â€Got any nails?â€
Confused, the bartender says no.
â€Good!â€ says the duck. â€Got any grapes?â€
