A Duck Wants Too Know:
A duck walks into a bar and asks, "Got any grapes?"
The bartender, confused, tells the duck that no, his bar doesn't serve grapes.
The duck thanks him and leaves.
The next day, the duck returns and says, "Got any grapes?"
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: "Listen, you fucking duck! This is a bar! We do not serve grapes! If you ever ask me for grapes again, I will nail your stupid duck beak to a bar stool."
The duck is silent for a moment, and then asks, "Quack, do you got any nails?"
Confused, the bartender says, “Hell no, I don’t have any frigging nails you stupid damn duck.”
"Very Good!" says the duck. ''Quack, got any grapes?''
