Following a string of advertising-based hallucinations, Homer impulsively decides to go to clown college and become a Krusty impersonator. Meanwhile, the real Krusty is trying to dodge the Mafia after making some bad bets.
- 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
- Blatant Lies: A man at clown college dressed like a Texan claims to be from Brooklyn because he's not the only Texan there and there can be only one Krusty impersonator per state.
- Chekhov's Skill: Inverted; it's Homer's inability to ride a mini bicycle through a loop that resurfaces -and almost gets him killed- by the end of the episode.
- And subverted when Homer suggests that instead of performing that particular trick he could squirt Don Vittorio with his button (it was his major); it's the loop or death.
- Comically Missing the Point:
- While all the other clown college students inform Krusty where they're from, Homer just says his name.
- After Krusty reads the joke names of certain towns, Homer inexplicably finds the most normal one, Seattle, to be hilarious.
- Homer beats up an actor, portraying a burglar to amuse the children in the audience, not understanding that it's obviously an act.
- After Krusty obviously runs out on them, Legs says he needs to use the bathroom next. This causes Fat Tony to roll his eyes.
- When Homer tries saying he's not Krusty, one of his given aliases is Benedict Arnold. Louie seems to honestly think Homer means he's the Benedict Arnold.
- Department of Redundancy: Homer: "Who am I clowning? I have no business being a clown! I'm leaving the clowning business to all the other clowns in the clowning business."
- Digging Yourself Deeper: As Homer tries to tell Fat Tony he isn't Krusty, everybody he tries to say he is, including himself, has upset Tony one way or another.
- Even Evil Has Standards: After nearly being killed for not paying his debts Krusty pays the money anyway, which turns out to be the ridiculously low sum of $48. The boss is happy and even gives him back his change.
- Eye Scream: Krusty cautions his students to be careful with their balloons, because if one goes off it'll take out the eyes of every kid in the room... then he asks his accountant how much that cost them.

- 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!"
- Kill the Cutie: An Estonian little person (not the one who played Lisa in the fake video of The Simpsons talking about how they don't miss Bart, though he does have the same voice as him), dressed up as a thief character to amuse the young audience is brutally beaten to pulp by Homer, who doesn't get that it's supposed to be an act.Kid: (crying) Stop! Stop! He's already dead!
- Let Me Get This Straight: One from Krusty's accountant.Accountant: Let me get this straight; you took all the money you made franchising your name and bet it against the Harlem Globetrotters?!Krusty: Oh, I thought the Generals were due!

- 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).
- Pocket Protector: Two of them save Flanders from being killed by Mafia hitmen trying to hit the man standing next to him.*Gunshot* (Flanders is knocked down)
Ned Flanders: Whew, good thing I always keep a Bible next to my...

- Homer and Krusty drive a mini bicycle together, causing Homer's head to bump against some glasses and quote the theme from The Godfather.
