Episode #213 "Proud Dick"

Dick quits his job on principle when the university president refuses to give him a better parking space, and he's forced to take a job at Rusty's, a fast food restaurant much like McDonalds. Dick feels his new job is beneath him, and his arrogance earns him several demotions, while Sally struggles to make ends meet at home. Harry is swept off the roof by a tornado, and a knock on the head makes him lose his memory; when he returns home, he's terrified to discover that he's living with a group of aliens. Dick realizes that has to have his old job back, so he grudgingly apologizes, but he still isn't satisfied with his parking space. And it takes being struck by lightening to make Harry return to his "normal" self.
