A duck walks into a bar and asks, “Got any crackers?”

The bartender says, “No.”

The duck walks out, but he walks in the next day and asks, “Got any crackers?”

The bartender says, “No.”

The duck walks out, but he walks in the following day and asks, “Got any crackers?”

The bartender says, “I told you yesterday and the day before that no! And if you ask that one more time I’ll nail your beak shut!”

The duck walks out again, but he returns the next day and asks, “Got any nails?”

The bartender says, “No.”

The duck says “Good. Got any crackers?”
