To pay for Princess' stabling, Homer moonlights at the Kwik-E-Mart, which exhausts him over time. Marge tells the children about the sacrifices their father is making, but says that Lisa must decide for herself whether to part with Princess. After watching Bart take advantage of a sleep-deprived Homer at the Kwik-E-Mart, Lisa shares a heartbreaking goodbye with her pony. She tells Homer there is a "big dumb animal" she loves even more than Princess: her father. When Homer quits his job at the Kwik-E-Mart, Apu admits he was one of his best employees, despite being crude and lazy.
