Leon Kompowsky, a "big white guy who thinks he's the little black guy", is a mental patient who thinks he's Michael Jackson, but later confirmed that he knows he's not Michael.
Leon Kompowsky worked as a bricklayer in his early life and was angry about himself until he started impersonating the voice of Michael Jackson, which gained him respect. He was placed in New Bedlam Insane Asylum where he later met Homer, who got hospitalized for wearing a pink shirt to work. Leon impersonated Michael Jackson though Homer had no clue who Michael Jackson is. After getting released, Homer invites him to come visit his home (Kompowsky was in the hospital voluntarily) and Bart, thinking Kompowsky is the real Michael Jackson, tells everyone. The entire town shows up to see Michael Jackson, only to learn it's fake. Bart becomes hated in the town, and Lisa hates him too for forgetting her birthday. Kompowsky decides to set things right and helps Bart write a special birthday song for Lisa. In the end, his work is done, so Kompowsky drops the Jackson charade and starts talking in his normal voice, citing his reasons for doing the voice was a result of anger and he felt respected when he did the Jackson impersonation, he then cites his work at the Simpson home was done prior to leaving.
