Ah, Las Vegas. Not as much fun for me anymore since I figured out how to win at video poker and they kicked me out. And not so much me, but I was trained in the family business, as it were. My father and uncle hunted things that needed killing. Wendigos, yetis, poltergeists, werewolves, unruly vamprires, you get the idea.
Oh, see, morals are subjective, so it depends on to whom you're speaking with.
