Traditional (German folktale) Hamelin town is overrun with rats and the people are very unhappy that the mayor has not solved the problem. A strange piper comes to the mayor's office and offers to rid the town of rats for a thousand gold coins. The delighted mayor says he'll give him 50,000 coins. The piper plays a tune and the rats follow him to the River Weser where they all drown. The people are happy, but the mayor does not pay the piper his price. Next day the piper plays another tune and all the children follow him away into a mountain. The unhappy people of Hamelin learn that you must always pay the piper his fee.
