Got any gwapes?

A duck walks into a record store. He jumps up into the counter and asks the clerk "Got any gwapes?"

The clerk, taken slightly aback by the taking duck, says "Uh, no, man, this is a record store. We don't sell grapes."

The duck simply says "Ok," hops off the counter, and waddles out the door.

The next day, the duck once again walks into the record store, hops up on the counter, and asks the clerk "Got any gwapes?"

The clerk cocks his head and says "Uh, sorry dude. Like I said yesterday, it's a record store. No grapes."

"Ok," says the duck happily. Before hopping down and waddling out of the store.

The next day, the duck strolls casually into the store, hops up on the counter, and asks the clerk "Got any gwapes?"

The clerk sighs loudly, frustrated. "Look man, I've told you three days in a row now. This is a record store! We don't sell fucking '*gwapes*.' If you come in here one more time asking for grapes, I'm gonna nail your fucking feet to this counter!"

The duck simply replies "Ok," before hopping down and waddling out the door.

The next day, the duck walks into the store, hops up on the counter, and says to the clerk "Got any nails?"

The clerk looks at the duck for a long time before saying "This is a record store, of course we don't have any nails."

The duck says "Ok. Got any gwapes?"
