A certain character, wronged (for real or in his own mind?) so many years ago, forms an uneasy alliance with Bart to open (spoiler alert!) a fast-food chain that competes with his original nemesis. Hilarity ensues as this character spirals down on his helicopter moptop of ever-increasing hubris and rationalizations. In the end, in one last selfless act, he shields Bart from (something, I dunno - we'll get to that after lunch) and dies, kinda-sorta, by his own doing.
