Overview: The Simpsons' roof springs a leak when the perfect storm hits Springfield. And when Marge asks what type of father can't keep a roof over his family's head, Homer tries to fix things up, but falls through the roof. Sick of being unwanted, Homer befriends a man who works as a roofer. However, no one else can see him and Homer's insistence that the roofer does exist prompts everyone to think he has gone crazy.
