Wing Commander, I heard that story, told slightly differently years ago too.
BTW does any one remember the one about the Siamese twins, one became a brother and the other one didn't? Then he kept hearing stuff and eventually converted.
What about the one where the child came to the door and said that mummy wasn't home but they could see her feet behind the glass panel at the side of the door so they said to the child, "You tell mummy's feet that we called.".
Heard all this stuff so many times told in slightly different ways.
