As Chachi and Fonzie begin to leave the boxing ring for Arnold's, somebody can be seen running through the shot in the bottom-left corner of the screen.
Chachi references Fonzie working at Patton Vocational High School. However, this episode aired before the episode where Fonzie begins working there.
The boxing arena used in this episode is the same boxing arena used in the season 5 episode "Requiem for a Malph."
Anson Williams does not appear in (at least) the syndicated version of this episode.
The title is a pun of Love Story, a famous movie based on the book by Erich Segal.
