Legend of the Irish Pot of Gold
Legend tells us the wee Irish folk called leprechauns make fairy shoes for a living. They are said to stash their gold in a pot at the end of a rainbow. The best way to find a leprechaun is to follow the tap of a shoemaker's hammer. If you catch him, he must take you to his treasure if you can keep him in sight. If the leprechaun can trick you into looking away, he will vanish and so will hopes for finding the leprechaun's treasure.
