Quest Quest: The Sierra team makes a Quest game about how the entire team gets together and writes a Quest game. One of the puzzles is what to call the game: Quest for Quests? Questy Quest for Quests? How about Arthur? Or Harold? Harold sounds nice. Hang on, that's the Quest for Hero's Name. Completely different.
What shall we name the villain? How about Mahna-Mahna-Man? That sounds good, we'll go with that. Only we'll drop the "h"s or Jim Henson will sue. And change the "m"s to "n"s. Mananananan! There we go. Too confusing? Ergh, fine. We'll shorten it a bit. Manannan! Done! Now who's up for coffee and donuts?
