Somewhat on topic: There was another show on the SciFi channel called The Invisible Man. One of the characters, Eberts, was this little mild-mannered paper pusher. In one episode, a drug gets in his system that makes him totally freak out and go psychotic. The actor who played him (Mike McCafferty) wanted to show that Eberts was this total geek, so during the scene where the hero tries to save the day, Mike ad-libbed "Fawkes, I'm going to frelling kill you."
