Hey, remember...you invited me to do this!
1. Somebody asks a LotR trivia question.
2. You provide the answer, and ask another question.
3. Repeat step 2 above with other peoples' questions.
I'll start, just because. The initial question will be an easy one, so as to get the ball rolling:
What LotR character was Elrond's mother-in-law and Arwen's grandma?
This ought to separate the geeks from the boys...
Easy!
