Murder snails

I am currently staying with a friend of the family, who to my surprise has a murderous streak in her. She's engaged in a war. With murder snails. All of a sudden she disappears, bringing a pair of scissors. This afternoon she came back in, proudly claiming that she just killed 59 snails. In 8 minutes. She simply cuts them in half. It's not exactly like I like snails, quite the opposite actually, unless they are served on a plate with garlic sauce :)...but I would never kill them. I'm too squeamish. And they are really disgusting. At least what's left of them.
