As Woody preps for a sports trivia contest with Carla, he can't remember in what game Ted Williams broke his elbow (or even who Ted Williams was). The answer is the 1950 All-Star game in Chicago.
The title comes from Don Juan In Hell, a play within a play from the drama Man and Superman by George Bernard Shaw written in 1903. Man And Superman was referenced in a later episode when Robin Colcord purchased Shaw's desk for Rebecca. As well, Don Juan In Hell was used as title of an episode of Frasier (in which the title character has a series of surreal encounters with the women in his life, including Lilith and Diane).
Actor Kenneth Tigar appears in two episodes of Cheers as different characters: one, in this episode as Dr. Lowell Greenspan and as Fred in The Boys in the Bar (1983).
After the sports trivia contest with Carla, a spaced-out Woody continues misquoting random trivia he memorized. There is no record of a shortstop named Elmer Goodwoody ever existing and the actual 1959 winner of the California derby was Finnegan.
