D'oh moment

That loud noise just then was me doing a crossword puzzle and coming across the clue "stonecutter" and realizing how clever The Simpsons creators are. How many others did/not know that The Stonecutters of which Homer ultimately becomes leader before they reform the group to exclude him is actually based on the FreeMasons ... or Masons D'oh. I knew it of course, but I just hadn't put it all together in my conscious mind until the clues finally fell into place just then.
