The Simpsons Season 2 Episode 4

A three-eyed fish is caught in the Springfield River downstream from the nuclear plant, leading to a government safety inspection. When Mr. Burns is told that the plant will be shut down, he gets drunk in his car with Homer. Homer remarks that if Burns were governor, he could make new laws to keep the plant open. Burns seizes on this remark and announces his candidacy. Afraid for his job, Homer pushes his family to campaign for Burns, but Marge is a staunch supporter of the incumbent, Mary Bailey. On the night before the election, Burns dines at the Simpson home as a publicity stunt.
