"Grapes" joke

A duck walks into a bar, sits down at the barstool, and waits for the bartender.
The bartender walks up, hands the duck a menu, waits a while, and comes back to take his order. "
What'll it be?"
the bartender says.
The duck says, "
I think I'll have the grapes."
"
Well, I'm sorry sir, but this is a bar, we don't serve grapes here. Now, I'll let you look a bit longer and wave when you know what you want."
The duck looks at the menu, then waves the bartender down. "
Ok, you got your order?"
The duck nods, saying, "
I'll think I'll have the grapes."
The bartender, kind of peeved from the duck, says, "
Look Mac, we don't have any grapes here. This is a bar. We don't serve grapes, so what will you have?!"
The duck looks at him in the eyes and says, "
I'll have the grapes."
The bartender, enraged, shouts, "
If you ask for the grapes one more time I'm going to nail your feathered a%$ to the barstool!"
The bartender cools off a bit. "
Now what will you get?"
"
Got any nails?"
"
OF COURSE WE DON'T HAVE ANY NAILS! WHAT DO YOU THINK THIS IS? AN APPLIANCE STORE?"
"
Good, got any grapes?"
