First Aired - 2/3/1994
While on a boring field trip to the box factory, Bart makes a break for it to Channel 6 Studios, home of Bart's favorite show, Krusty the Clown, and gets a job as Krusty's assistant — then becomes an accidental star after screwing up during a live sketch and blurting, "I didn't do it!"
This episode contains examples of:
- 15 Minutes of Fame: Bart's fame wears off after a couple of weeks.
- Analogy Backfire: Bart is willing to listen to Homer's advice about not caring what others think until Homer says that's what made him what he currently is.
- And This Is for...: Nelson when he thought Bart was lying about being Krusty's assistant.
- Ascended Extra: In-universe. It takes Bart one clumsy entrance from being a Spear Carrier to become a main act in Krusty's show.
- As Himself: Conan O'Brien (the only Simpsons writer ever to come back and voice himself. Also, the only Saturday Night Live writer to voice himself on The Simpsons)
- Bait-and-Switch: Bart tries to use his imagination to fantasize about a better outcome like Lisa did after learning about a boring class trip to the Box Factory, but it gets him nowhere:Skinner: Instead of going to the box factory, we're going to the...box factory!
- Baleful Polymorph: Upon seeing his lucky red hat on top of one, Homer believes the factory machinery had cleanly transformed Bart into an ordinary cardboard box.
- Big Fancy House: Lisa has one in her imagine spot.
- The Bore: Only Principal Seymour Skinner would think it's a good idea to visit a box factory. Repeatedly.
- Bowdlerization: Thanks to the 2004 Indian Ocean tsunami, the parts where Kent Brockman is trying to read a report about a tidal wave in Kuala Lumpur, then changes it to France because he can't pronounce Kuala Lumpur and the Mexican Bumblebee Man reading the tidal wave report after Kent Brockman refuses to do it because his cheese danish was stolen are cut on the UK's Channel 4.
Lisa: "If I'm ever famous for something, I want it to be for something worthwhile and not just some stupid fad."
- This episode makes fun of the fact that people who become famous for blurting a catchphrase are only famous for a short time.
(Homer breaks a lamp.)Homer: D'oh!Bart: ¡Ay, caramba!Marge: Hmmmm...Maggie: (suck suck suck)Flanders: Hidely-ho!Barney: (belch!)Nelson: Haw-haw!Mr. Burns: Excellent!(beat as everyone looks at Lisa)Lisa: If anyone needs me, I'll be in my room.(she leaves)Homer: (over the credits) What kind of catchphrase is that?
- ...and then parodied when every character on the show ends up saying their own catch phrase in rapid succession.
- And it becomes apparent that Lisa is the only main character without a Catch-Phrase.
- Celebrity Is Overrated: Bart at first loves the fame and attention it gets him, but eventually gets sick of the fact that he's treated as a one-trick pony.
- Chirping Crickets: When Bart does his line and the audience is not reacting, we hear this sound.
- Class Trip: The episode begins with Bart's class going on a trip to a box factory. On the way, they pass in front of a "Toy Town", a fireworks testing range and a slide factory, all of which have other schools' buses parked outside.
- Closed Door Rapport:
- Bart refuses to come out of his room to do another appearance on the Krusty Show. However, Marge changes his mind talking to Bart from behind the door.
- Sideshow Mel shouts at Bart from behind the bathroom door.
- Continuity Nod: When Bart is trying to get Krusty to remember him, he mentions how he saved Krusty from going to prison, reunited him with his father, and helped him put together his comeback special. In spite of all that, Krusty has completely forgotten about meeting Bart before.
- Credits Pushback: Done to Krusty's show; this results in Bart's name being hard to read when the tape is paused, and his friends don't believe that he actually works on the show.Nelson: (after punching Bart in the gut) That's for taking credit for other people's work.
- Dead Hat Shot: Bart tossing his red baseball cap on to a cardboard box when he ditches the Class Trip to the box factory leads Homer to conclude that he has been made into a box.
- Department of Redundancy Department:Bart: It's my job to be repetitive. My job. My job. Repetitiveness is my job! I'm gonna go out there tonight and give the best performance of my life!
Marge: The best performance of your life?
Bart: The best performance of my life!
- Field Trip: The episode begins with Bart's class going on a trip to a box factory. On the way, they pass in front of a "Toy Town", a fireworks testing range and a slide factory, all of which have other schools' buses parked outside
- Game Show Appearance: Bart dreams he's a panelist on Match Game 2034. He ends up knocking over, and breaking, Kitty Carlisle's head-in-a-jar.
- The Guards Must Be Crazy: Parodied with that guard on the studio set who lets Bart pass on his word that he works there.
- Happy Place: Lisa doesn't want to leave her Imagine Spot because she likes being in it too much.
- Horrible Hollywood: Bart is exposed to the full force of showbiz, "a hideous bitch goddess".
- Hostility on the Set: Yet another In-Universe example courtesy of Kent Brockman, who absolutely refuses to do his work as a newscaster because someone stole his danish and says so on live television, which leads to the producers immediately kicking him off the set and replacing him with Bumblebee Man.
- Hypocritical Humor: At the end of act three:DJ 1: And that was "Kung Fu Fighting". Speaking of "one trick ponies", whatever happened to that "I didn't do it" kid?
DJ 2: Boy, did that get old fast! WHOA! Y'know, if you wanna last in this business, you gotta stay fresh! (plays recycled sound effects)
- I Can't Believe I'm Saying This: When Bart's entire class is waiting for him to say his new catch phrase.Bart: I can't believe I'm saying this, but...shouldn't we be learning something?
- Imagine Spot:
Skinner: Class, instead of the box factory, today we'll be going to the..... box factory.
- Lisa has a rather disturbing imagine spot where she kills Bart with her Nobel Peace Prize.
- Bart has one when he tries to imagine a place he'd rather be instead of the box factory. It backfires when he can't think of anything else.
Bart: Damn TV, you ruined my imagination, just like you ruined my ability to... to um... oh well. (pulls out a mini-TV and laughs while watching it)
- Implausible Deniability: When Bart accidentally destroys Krusty the Clown's set in front of a live audience, his attempt to deny it spawns the Catch-Phrase "I didn't do it".
- I'm Standing Right Here: Lisa gives a disgusted tirade on Bart's popularity and claims she'd loathe to be remembered for a mere obnoxious fad. When a hurt Bart is revealed to have entered the room, she awkwardly looks away and reads.
- Instantly Proven Wrong: When Krusty declares that Bart doesn't have it as a star after ruining his set, he opens the door only to bump into a crowd of people waiting to see Bart.
- Interrupted Bath: When Bart wanders off from a field trip, and Principal Skinner calls Marge at home, causing her to run to the phone dripping wet in a towel. When she doesn't answer on time, he calls Homer at work, where, for some reason, he also runs for the phone after a shower.Homer: You'll have to speak up, I'm wearing a towel.
- Ironic Echo: "I wish I was dead."
- Irony: In her Imagine Spot, Lisa remarks how ironic it is that she impaled her brother on her Nobel Peace Prize.
- Leno Device: Conan O'Brien appears in his show with Bart as his guest. Considering Conan has written more than a few episodes of The Simpsons, it's appropriate.
- Lost Food Grievance: Kent Brockman really loves danishes. When Bart swipes Brockman's danish (which resembles more of a cinnamon roll) to give to Krusty, Brockman discovers his pastry missing and won't do the news report.
- Modesty Towel: When Homer comes out of the shower at the nuclear plant to answer the phone: "You'll have to speak up. I'm wearing a towel."
- Negative Continuity: "I didn't do it" was a Catch-Phrase of Krusty's in Season 1 episode "Krusty Gets Busted". He uses it in his show, it's one of the recordings on his doll, and the crowd laughs when he meekly says it after getting arrested. In this episode, it's Bart's brainchild.
- No Celebrities Were Harmed: Dan Castellaneta based the box factory manager's voice on Wally Ballou, a character portrayed by Bob Elliott of the comedy duo Bob and Ray.
Bart: Wow! A big clown hankie.
- For this episode's chalkboard gag, Bart writes that his homework wasn't stolen by an one-armed man.
- To escape the box factory, Bart hides himself in a laundry basket, similar to Annie. The only difference is that nobody was there to take him out, so he just goes out through a nearby door.
- The scene where Krusty makes Bart his assistant by entrusting him to wash his towel is staged like the classic Super Bowl Special by Coca-Cola where a boy gives Mean Joe Green his Coke and starts to walk off, only to get Joe's towel in return.
Krusty: It's a towel, you yutz!
- The "I Didn't Do It" dancers are clearly based on the Fly Girls from In Living Color!.
- Skyward Scream: Homer sends one out after he believes his son was turned into a box.
- Theme Tune Cameo: Marge asks Bart to stop whistling that annoying tune after hearing him whistle The Simpsons theme song while coming into the kitchen.
- Troubling Unchildlike Behavior: Lisa fantasizes about killing Bart in her fantasy.
- You, Get Me Coffee: This is what Bart's career amounted to at first, nearly driving him to quit. Then he has to fill in for Sideshow Mel and the rest is history.Krusty: This is a dream factory, the birthplace of magic — an enchantment! Now I need you to go clean out my toilet.
