A duck walks into a bar and asks the bartender "Do you have any bread?". The bartender answers no, but a few minutes later the duck asks the same question.


"I already told you, no, we don't have any bread". Still, a few minutes later, the duck, once again, asks for bread.


"Listen, duck, if you ask me one more time if we have bread, I'm gonna nail your bill to the bar!"


The duck asks "Do you have a hammer?"


"No"


"So, do you have any bread?"
