Sideshow Mel tells the story of how Lisa upstaged Krusty the Clown on his own show. Meanwhile, Bart and Homer go coin-collecting.

!!!Tropes:
* ExplainExplainOhCrap: As Krusty's agent warns him that Lisa will try to sabotage his career, he gets a call from Mr. Teeny,
-->'''Krusty:''' If there was a rehearsal for the network, I would have been told by my...''(gasp)'' assistant!
* HowWeGotHere
* OrbitalShot: Lisa when she experiences the sensation of applause for the first time.
* ShoutOut
** Krusty's "Krustkateers" are an obvious parody of ''TheMickeyMouseClub''.
** Bart's act involves him swallowing light and lighting up his stomach, saying he's [[ETTheExtraTerrestrial E.T.]] He then puts on an afro wig and says he's [[Creator/{{BET}} B.E.T.]]
** Krusty's dog costume at the end greatly resembles Nana from ''Disney/PeterPan''.
