Features the first appearance of Harry Anderson as Harry the Hat since season 2 - and the last appearance until late in the final season. Anderson had moved on to star in his own series, Night Court (1984).
At one point in the episode George Wendt's character gets a lemon stuck in his mouth. Five years prior he had a brief appearance in a M*A*S*H episode (Trick or Treatment, season 11, episode 2) in which he gets a billiard ball stuck in his mouth. Some lessons learn hard.
In an earlier episode Norm pays down some of his bar bill by painting Rebecca's office. The paint, which is applied to a small area, is a light sandy brown. In this episode her office is pink again. While the producers obviously did not want to paint the entire set, one could say that Rebecca changed her mind.
