Billy Bob Golo was a direct descendant of the Olog-hai created by Sauron. You know, that evil guy in the Lord of the Rings. What that meant was that he wouldn't turn to stone in the daylight. Generally, that's what happens to trolls.
Well, Billy Bob's best friend happened to be Dracula the Younger, son of Dracula. You didn't know Dracula had a son? Anyway, Billy Bob and DY always played at night because that's what vampires do. So, Billy Bob always slept during the daylight hours.
Well, one night Billy Bob went into town to wait for DY and DY didn't show. Billy Bob fell asleep on a bench and when daylight came, Billy Bob found out he wasn't a descendent of the Olog-hai. True story.
