"Troll - A supernatural creature of Scandinavian folklore, variously portrayed as a friendly or mischievous dwarf or as a giant, that lives in caves, in the hills, or under bridges."

The only real troll I've ever met was the Bridge troll in the Three Billy Goats Gruff. I could never figure out just what was so terrible about him. Only he lived under a bridge and the billy goats were afraid of him. Mind you, I'm only always reminded of this by this term 'internet troll.' I don't mean to throw some charmed Poly-Anna dust on any possible goings on about whose existence I am utterly unaware. This is really and truly a separate matter of which I am once again reminded: I just always wondered about trolls, that's all. I just don't get 'em.
