Ritchie's teacher has instructed the boy to learn a new word a day. Taking the assignment to heart, Ritchie (Larry Mathews) shocks his parents Rob (Dick Van Dyke) and Laura (Mary Tyler Moore) by blurting out a word that, to put it mildly, was not uttered in polite company (or on TV!) back in 1961. Taking it upon himself to counsel Ritchie about his choice of language, Rob only manages to make the situation worse -- and just wait until he meets the parents of the kid who taught Ritchie the forbidden word!
