Bart becomes an instant celebrity after he ad-libs a line during a sketch on the “Krusty the Klown Show.”
Bart’s class takes a field trip to the local box factory. Bart becomes bored and sneaks away to the nearby television studio where the “Krusty the Klown Show” is taped. Meanwhile, Homer arrives at the box factory after his son turns up missing. Homer finds Bart’s red cap in a box and fears his son has fallen into the machinery. After Krusty fires his intern for not being able to supply him with a Danish, Bart steals a pastry from Kent Brockman and gives it to Krusty. The grateful clown hires an ecstatic Bart as his new intern.
Bart’s view of showbusiness soon sours. His on-screen credit is so small his friends cannot read it, and gets stuck he signing Krusty’s autographs for his fans. Disillusioned, Bart decides to quit. But Krusty offers him a one-line bit part in a comedy sketch. Bart accepts, and while on-stage he trips over a prop and causes a near disaster. Instead of saying his line, Bart says “I didn’t do it.” The audience goes wild and he becomes an instant celebrity.
Bart’s “I didn’t do it” line becomes a catch phrase, and the boy’s image is soon imprinted on record albums and many other product tie-ins. Bart overhears Lisa call his stardom an obnoxious fad, and while appearing as a guest on the “Conan O’Brien Show,” unsuccessfully attempts to disprove the allegation. Bart tells his mother that he will give the best performance of his life on an upcoming episode of Krusty’s show. But when his moment comes, the audience does not laugh. Bart is puzzled by the response. Krusty tells him that his stardom has ended, attributing it to the unexplainable nature of show business.
