What is Bart's catchphrase when he stars in the The Krusty the Clown Show in the episode "Bart Becomes Famous"?

Airing in the fifth season of the series, in "Bart Gets Famous," Bart gets a job as Krusty the Clown's PA. While working there, he replaces Sideshow Mel in one of the skits and, true to form, destroys the stage props. When he instinctively says "I didn't do it," that becomes his catchphrase and it makes him famous.
