Voodoo doll

It did not look like much. Just a small rag doll.

The doll, however, had been blessed, or cursed depending on your point of view with the ability to transfer feelings, sensations, and even movements from the doll to a person. All the doll's owner needed was a strand of hair from the person and to say an incantation.

The doll's owner had obtained a strand of hair from a famous celebrity, applied the hair to the doll and said the incantation.
