- Affably Evil: Don Vittorio DiMaggio apologizes as he is about to shoot Homer (believing him to be Krusty) and decides he won't do it on the condition of having the "Spin-Cycle Fantastic" trick performed for him (which Homer fails); then apologizes again when the real Krusty shows up at the last second, and ultimately lets them both live when they successfully pull off the trick together.
- Arson, Murder, and Jaywalking: Homer's reasons why it sucks being a clown: "You get kicked by kids, bit by dogs, and admired by the elderly."note

- Is It Something You Eat?: When Homer goes by the new billboards, the first few ones are of food, so when he comes to the one for Clown College, he complains "Clown college? You can't eat that!"

Stop! He's already dead!

- Plot Hole: Milhouse really had no reason to gloat about having Krusty over at his party — Bart already had Krusty over for dinner at his place in "Like Father, Like Clown" (and Milhouse was at the Simpson house with Krusty, so that's really bad that the writers would make Milhouse out as a braggart).
