@ray_afraid, I will update when not at work. But how would you define them? According to Wikipedia, they at least started as a ska band.

@Dur, missionaries at the door are often mistaken for Kang and Kodos ;)

@Boost, now I can't help but wonder if you're cheating by looking them up. That said, I believe there is at least one other prominent serial killer (I'd have to look up who, since I've forgotten) who is Mormon. Another infamous example is Butch Cassidy.

JEDIT: Now I know you're not cheating because I tried to look up Shelton Young and can't find anything. Are you making that one up?
