LOL - I've written this before somewhere here - my Mum was a little girl in England and consistently had a huge wart growing between the knuckles on her hand.
It would grow so large that it would get 'knocked' off while she was playing, it was painful and would bleed.
My Grandmother took her to the 'witch doctor' in the village who was known to cure all kinds of ailments.
This woman told my Mum to take a potato that evening, cut it in half, rub both halves on the wart, put the halves together, and then bury the potato in the garden after dark.
Well of course she did this, but didn't expect much - but on waking the next morning, this huge wart was gone!
My Mum said she searched the bed looking for it, but never found anything, and the wart never returned.
How do things like this work, anyone know??
