Hank Kimball's dog is an Irish Setter named Quincy.
Arnold and Cynthia bark and oink at each other during their break-up scene. Subtitles of what they are saying are shown on-screen.
Lisa likens the difficulties of Arnold and Cynthia with their fathers to those of Romeo and Juliet, or as she says, "Romeo and Julius."
Lisa's rendition of lines from William Shakespeare's "Romeo and Juliet" is, of course, another example of her penchant for malapropism. When she says what sounds like, "Romeo, Romeo where art force thou?" and "But soft! Who broke that window with the light yonder," as well as, "It is in the east and Julius has a son," she is misquoting the actual lines of "Romeo, Romeo, wherefore art thou Romeo?" and "But soft! What light through yonder window breaks. It is the East, and Juliet is the sun." The lines all come from the famous balcony scene in Act II, Scene 2 of the play.
Cynthia's fiancé, according to Mr. Haney, is named Grover, who lives in Crabwell Corners. The combination of the names Grover and Crabwell Corners smacks of an allusion to the fictional town of Grover Corners that Thornton Wilder created for his play "Our Town" first performed on Broadway in 1938 and subsequently adapted to the screen for the movie of the same title: Our Town (1940).
