The next full moon, cut 1/4 of an onion and rub it on the wart. Ties a string around the onion piece, bury it in a hole and walk around the hole 3 time (I can't remember if it's clockwise or counter clockwise, so do both directions.) Wart will be gone in a few weeks.

How's that for voodoo?

My mom had me do this when I was in HS and it actually worked!
