Chachi remarks that Fonzie only has two boxes of belongings after living in his apartment for six years. However, he moved in at the start of the third season, so, at this point, he had lived there for about eight and a half years.
Fonzie: (to Marion) You think there could ever be a time when you needed me, and I wouldn't be there for you? (pauses and looks at Howard) Why are you so glum, Mr. C.?
Howard: I just can't believe that the Braves are moving to Atlanta.
Anson Williams does not appear in (at least) the syndicated version of this episode.
