Wikipedia: Rabbit’s foot
In some cultures, the foot of a rabbit is carried as an amulet believed to bring good luck. This belief is held by individuals in a great number of places around the world, including Europe, China, Africa, and North and South America. This belief likely has existed in Europe since 600 BCE among Celtic people. In variations of this superstition, the donor rabbit must possess certain attributes, have been killed in a particular place, killed by a particular method, or by a person possessing particular attributes (e.g., by a cross-eyed man).
