I like vampires in the Pratchett universe, who often see human hunting as a sport and leave religious symbols, stakes, and garlic around the castle to level the playing field. (Not to mention the black ribbon society, the vampire equivalent to AA.)
Germany reporting in: There are bushes in nearly every park in nearly every city over here where men are waiting to suck off other guys. No joke. That's the reality.
Yeah, but what quality blood are you getting? Vampires hunt. They select. "hey come lookitthis afore I flush it!" is going to get you some dudes, but they're gonna taste bad.
