On a Mandolin slicer.
My girl friend decided to thick slice a sweet potato for Christmas dinner.
She decided the guard wouldn't hold the huge potato so attempted it free hand.
She ended up in the emergency ward when she took off 3/8 of an inch of her thumb and
almost all the nail.

I'm not sure I can continue to date her now that she's disfigured.

If it wasn't for the Lee Valley catalogs I never would have bought the evil thing.
I might sue...for 3 weeks of lost foreplay.
It was the thumb on her most talented hand...
