The Generation Gap Widens

SO. I was watching Prison Break (it's on UKTV Gold) last night, and one of the characters was talking about how he had made a knife that would pull out the victims intestines (that's a wound, it'll bleed and bleed). To which another character replied "you're one sick puppy".

My mother found it hard to understand why developing a knife designed to inflict the maximum amount of pain would be considered sick. This is a woman who criticises me for believing in private healthcare, but who has no problems with prisoners torturing each other.
