I will nail your

A duck went into a bar and asked for some crackers. The waiter said no.

The next day he came into the bar and asked for crackers again.

The waiter said no, again.

The next day he came in again and asked for crackers.

The waiter said no.

The next day the waiter said if you ask for crakers one more time I will nail your beak to the counter.

The next day the duck asked if the waiter had any nails, "No," said the waiter.

The duck then asked "Do you have any crackers"
