I have a neighbor who is an insufferable "Prius prophet" and won't quit raving about his Prius. He once proudly asked me how I liked his car and I replied, "The Prius isn't a car, it's an appliance". He's barely spoken to me since, except to inquire whether it's legal to drive my SPFGT40 on public roads. I HAVE to email that link to him!
On second thought, if somebody gets fed up and clips him I'd end up being a suspect. :-(
