Black cats and voo-doo dolls?

Superstitions, I am not a strong believer in these petty things. I have a black cat, and it doesnt give me bad luck. I don't think that voo-doo dolls could actually work on a person, I don't actually know of any real situations where a doll was made of a person and worked. I admit that when i was younger i got mad at my friend Jesse for stealing my Gameboy so i thought i could make a voodoo doll of him to get back at him but to my dissapointment it failed. So When it comes to superstitions i kind of don't really pay any close mind to them because i have never experienced any wierd superstitious events.
