When Bart's birthday party turns into a disaster, he uses his AM radio gift to play pranks on the townspeople. Eventually he uses it to pretend to be a boy stuck in a well, and the whole town comes to his aid.
Everyone at the powerplant thinks Homer is crazy when he shows up in a pink shirt and want to give him a mental health exam. He has Bart take it for him and ends up in a looney bin with Michael Jackson.
Bart: Rod, Todd, this is God! Rod: How did you get on the radio? Bart: What do you mean "how did I get on the radio?" I created the universe, stupid kid. Todd: Forgive my brother, we believe you! Bart: Walk through the wall; I will remove it for you! (bumps) laterha, ha, ha!
