This episode was taped on February 20, 1987.
These are the final appearances of Dorothy's daughter Kate and son-in-law Dennis. They are played by a different actor-actress duo than their prior appearance, however.
Dorothy and Stan talk to Dennis on the lanai in one scene. This is a call back to the season one episode "Guess Who's Coming to the Wedding?", in which Dorothy and Stan talk on the lanai. Incidentally, "Guess Who's Coming to the Wedding?" featured Dennis and Kate's introductions.
In one scene, Sophia talks with Dorothy about a dream she was having about being stranded on a desert islanad with Cesar Romero. Cesar Romero would appear as her boyfriend Tony in the season five episode "Girls Just Wanna Have Fun... Before They Die."
Rose: (on I Love Lucy) You know, I'm still a little confused. Who exactly is Ricky?
Blanche: Lucy's husband.
Rose: I thought Desi was Lucy's husband.
Blanche: Not on the show.
Rose: Desi wasn't on the show?
Blanche: Desi played Ricky!
Rose: Who did Lucy play?
Rose: I know, but who did she play?
Rose: Right, but who did she play?
Blanche: Lucy played Lucy!
Rose: Well then why didn't Desi play Desi?
Blanche: ...he wasn't tall enough.
Dorothy: Oh, I remember when Stanley told me he was having an affair. It was at least 24 hours before I cut the crotches out of all his slacks.
Blanche: You didn't!
Dorothy: I was teaching English Lit at the time. Symbolism was my life.
When Dorothy and Kate are in the kitchen talking about Kate taking Dennis back, Sophia is sitting at the table. Depending on the shot, a bowl of grapes may or may not be in front of her.
