Maggie tells Carol, "When adults talk to adults, sometimes they yell. Haven't you seen the new Jack Klugman show?" The show she is referring to is a short-lived sitcom called "You Again?" in which Klugman played John Stamos's father. It was canceled after 2 seasons.
When Jason tells Carol "don't be a fool, stay in school" he says it in Mr. T's voice, who at the time in the mid 80s, used the slogan and his popularity to advocate for the importance of education.
