Guest-star questions

What was the last episode to feature no celebrity guest stars? How many episodes in season twelve featured no celebrity guest stars?

12-21-Simpsons Tall Tales had no guest stars. Other episodes in season 12 that had no guest stars (not counting Marcia Wallace, who I think should be an Also Starring anyway): 12-20-Children of a Lesser Clod 12-17-Simpson Safari 12-09-HOMR 12-08-Skinner's Sense of Snow 12-01-Treehouse of Horror XI

While I'm writing this, I'll say that I enjoyed tonight's episode, especially for a CABF. Homer's voice seems to have stopped its constant whine, Maggie was there and actually had a small part, and it was a good use of a guest star...or at least, not a bad use. When I was checking the season 12 episodes to see which had guest stars, I noticed that many had stars that either played someone else or had a cameo as themselves, which I think are the best kinds (rather than turning it into a celebrity bonanza). That's all.
