Lisa’s Pony is the eighth of Season 3. The episode aired on November 7, 1991. The episode was written by Al Jean and Mike Reiss and directed by Carlos Baeza. The episode features references to films such as The Godfather and 2001: A Space Odyssey and the comic strip Little Nemo in Slumberland.
Homer makes up for his latest example of fatherly ineptitude (failing to get Lisa a saxophone reed in time for the school talent show) by buying Lisa the one thing she’s always wanted: a pony. But keeping the animal ends up costing the family money and Homer takes a second job at the Kwik-E-Mart to make Lisa happy.
