First appearance of Gary and Gary's Old Towne Tavern. It also establishes the rivalry between his bar and Cheers which would resurface again from season six onwards.
Sigma Chi Fraternity is mentioned. Woody Harrelson is a member of Sigma Chi.
Woody is traumatized by a bowling accident in his youth. Woody Harrelson would later go on to star in Kingpin (1996), a movie about a bowler who gets maimed at the alley.
Kim Waltrip plays a woman at the bar who uses Cliff's sun glasses as a mirror while applying her lipstick. Several sites report, incorrectly, that Kim's role was that of Tawny, the sexy bowler on Gary's team.
This is the first appearance of Joel Polis as Gary. He would appear in two more episodes (S7.10 and S9.2). Gary was also played by Robert Desiderio in (S6.23, S10.7, and S11.19). Due to the infrequency of the appearance of the character, few viewers ever realized he was played by two actors.
