The Simpsons Episode 5.07 Bart's Inner Child

Homer and Marge are entranced by a charismatic self-help guru named Brad Goodman. While attending a Brad Goodman seminar with his parents, Bart is asked to appear on stage with the man himself and, as usual, misbehaves. Rather than be annoyed by Bart's sarcastic comments, Goodman uses Bart as a role model for his audience, a boy completely unafraid to listen to the squeaks and squawks of his "inner child." The people of Springfield take Goodman's words to heart, hosting a "Do What You Feel Festival." James Brown sings at the festival, but things go terribly wrong when the stage collapses because the carpenter responsible for building it didn't "feel" like making it sturdy. Soon, everyone realizes that the only person who can truly be like Bart is Bart himself and go back to repressing their inner children.
