The Simpsons: Homer Knows Best

Lisa has a crush on her substitute teacher; Bart decides to run for class president.

Homer fails a quiz designed to test how well he knows his son. A trip to the Fatherhood Institute convinces him to help Bart build a soapbox derby racer, but Homer's assistance only makes things worse. Riding a sleek racer designed by Martin Prince, Bart is thrilled to see his father come out to root him on.

Homer fails to buy Lisa a new saxophone reed and she is humiliated at a school concert. To make it up to her, homer buys her a pony, which lives in the Simpson house. To afford the pony, Homer must get a second job at the Kwik-E-Mart, and he can no longer sleep. Finally, Lisa relents and gives up the pony but keeps her father's love.

Grampa starts romancing an attractive woman at the retirement home, Zelda (Olympia Dukakis). When Homer refuses to let Grampa use his car for a date, Grampa steals Marge's car and takes Bart with him as he pursues Zelda to Branson, Missouri.

After disappointing Lisa on her birthday, Homer hires a private detective to get more information on his daughter. When Homer refuses to pay the bill, the detective frames Lisa for a crime, and Homer and Lisa must flee until they can prove their innocence.

When Homer does not respond enthusiastically to Lisa's heartfelt father's day gift, she becomes angry with him. To win back her respect, he becomes the Safety Salamander, a well-loved figure at Springfield Elementary. As the Safety Salamander, Homer becomes so popular, he becomes the leading candidate to replace Mayor Quimby in a recall election.
