Just Friends: Which is what Gary and Billie resolve to remain when they break up – apparently for good. (At least as far as viewers were concerned, as this ended up being the unannounced series finale.)
May-September Romance: Billie seems to prefer significantly older men, as she's dating a man, Rick, that is said to be Gary's high school classmate. note (Joe Penny, who played Rick, was actually just seven years older than Denise Miller, as opposed to the 15-year difference between Billie and both Gary and Joe).
Shout-Out: While this was at the time just the season finale for Archie Bunker's Place, there was a subtle hint that this was the finale, and it all comes full circle to the Archie Show's second episode 12 years earlier. In the tag scene, Archie is recounting a dream he had to Harry and reveals he woke up when he heard the toilet flush ... just like in the second episode where Archie flushed the toilet.
