Just so you know, I also caught a Tolkein reference on Who Wants to Be a Millionaire two weeks ago. If memory serves, the question was for $64,000 and was along the lines of:
This author’s work was the target of a parady entitled “Bored of the Rings”
The contestant did get the answer correct, after telling the audience that he had read both “Bored” and “Lord of the Rings”. Regis said that even he had read both and knew that the Harvard Lampoon wrote “Bored”!
The the way, if anyone has not read “Bored of the Rings” , they should. It is one of the most brilliant satires I have ever read.
