A duck walked into a post office and asked: "Do you have any soap?"
The man said no. We only sell postage stamps and envelopes. So the duck left.
The next day the duck walked into the post office and asked: "Do you have any soap?" The man replied no and if you come in here one more time asking for soap I will nail your beak to this desk.
The duck came back the following day and asked the man if he had any nails. The man said no so the duck said Ok, do you have any soap??
