Teacher's Pet - Season 2 Episode 10
Don't It Make My Brown Eyes Green

Scott teaches Leonard how to play fetch-- or fetch-it, after Leonard says its boring. That backfires the next day in school, when everyone is bored, trying to think of something to do. While Scott is off getting a drink of water, Leonard teaches everyone the game of Fetch-it-ball, which is just fetch, only with teams, and scoring. When Scott comes back from his drink of water and finds everyone playing fetch, hes surprised. When he finds out he didnt get any credit for fetch-it ... ball, hes even more surprised, and begins to get a little jealous. Later that day, while Scott tries to come up with a game to combat the ""grand game of fetch-it"", the fourth graders, led by Leonard, get pummeled by the fifth graders in fetch-it-ball.
