The legend of Henry Potter

As a young lad, Henry Potter was struck by a sharp table and got three stitches.
Then some guy came by and said,
"Never wondered how you got that mark on yer forehead? That was no ordinary cut. That's what yeh get when a powerful, evil coffee table touches yeh -- took care of yer mum an' dad an' yer house, even -- but it didn't work on you, an' that's why yer famous, Henry."
