The Andy Griffith Show (1960)

Season 3: Episode 23

Opie complains to Andy about how his new history teacher Ms. Crump is a mean old woman who likes to assign extra homework. Andy tells Opie it's not important if he doesn't know every answer, which leaves Opie believing history isn't important. Now Andy has to show Opie, and his class, how much history matters before Ms. Crump decides to quit.
