Two Cars in Every Garage and Three Eyes on Every Fish

S2 E4: When a three-eyed fish is discovered downstream from the Springfield Nuclear Power Plant, the plant is hit with tremendous sanctions by state regulators. Burns realizes that if he becomes governor, he could control the regulations and brings in a team of consultants to help him take on incumbent governor Mary Bailey. His climactic campaign event is dinner at the Simpson house where Marge – a Bailey booster – serves Burns’ own three-eyed-fish to him. Burns can’t eat it, destroying his image and costing him the election.
