Everyone must know this one by now, but…

A duck walks into a bar, and asks the bartender, “You got any duck food?”

The bartender says, “No, get out of here, we don’t have any duck food.” The duck leaves.

Next day the duck comes right back into the bar and asks, “You got any duck food?”

The bartender is pretty annoyed, and says, “No, we don’t have any duck food, get the hell out of my bar!” The duck leaves.

The next day the duck comes back again and asks, “You got any duck food?”

The bartender is livid at this point. “No! We don’t have any duck food, and if you come in here and ask that one more time, I’m gonna nail your little webbed feet to the floor!” The duck leaves again.

The next day, the duck comes back yet again and stands there staring at the bartender.

Finally the bartender can’t take it anymore and says, “Well?! Are you going to ask me the same question again?!”

The duck male reproductive organs its head. “You got any nails?”

The bartender is so surprised he forgets to be angry. “No, we don’t have any nails.”

“Well then… you got any duck food?”
