This is the second time in the series Mary and Lester miss going to Hawaii. In season 3's "Snowbound" their flight was canceled due to a blizzard.
Math error: When Travis breaks down how long 30 days is, he misspeaks the seconds as 2,000,592 seconds. It should have been 2,592,000 seconds. Stoney Jackson may have missed the word "thousand" in the take.
In one scene where Mary and Lester are watching television, the theme from The Jeffersons, Movin' On Up, plays in the background. Marla Gibbs starred on The Jeffersons before beginning 227.
Timeline Error: during their fight, Lester tells Mary he'll be heading to his mother's house. In the episode "The Class of '90" later in the season, it's revealed that his mother has been dead for 2 years.
Possible Goof: During Rose's flashback she is seen in apartment K, which is across the hall from apartment J (Sandra's apartment). Rose's apartment is supposed to be below Mary & Lester's, but Sandra's apartment is on a higher floor. Either this is a continuity error or Rose switched apartments later on.
Marla Gibbs and guest Franklin Cover worked on "The Jeffersons." She was the Jefferson's maid and he's the neighbor. In this episode he's the domestic and she's the one in charge.
The interaction between Mary and Thurmond in their first scene is pure "Florence and George" from Marla's and Sherman's days on The Jeffersons.
I recall that perhaps this episode was intended to feature Sherman Hemsley as Deacon Frye from "Amen" but that he did not want to appear on 227 as Frye. Sherman Hemsley appeared in another episode as a different character instead.
During the monopoly game Pearl rolls a 5, but her piece only moves 3 spots.
Jackee Harry won the 1987 Emmy for best supporting actress in a comedy for this episode.
Brenda's 15 in this episode (the 2nd season) but in the season before (season 1) she was only 13. How did she jump 2 years in one season?
This episode reunites Hal Williams and Lynn Hamilton, who portrayed Harley and Verdie Foster on The Waltons. The two actors also worked together in many episodes of Sanford and Son.
Marla Gibbs acted out the same "hammering the bell" scene four years earlier on The Jeffersons.
When Lester is bringing in the ottoman, his pants are unzipped.
Lou's efficiency was as big as the Jenkins apt, however, efficiencies are supposed to be rather small.
It's funny that Brenda does not want to be treated like a kid anymore because she is wearing pajamas with the feet attached.
Rose, Pearl and Sandra become angry that Mary mentioned them in her letter to the President, but didn't they hopefully ask Mary if she mentioned them at the beginning of the episode?
Notice that Sandra lives in apartment K. In "A Young Man's Fancy", the letter on the door is permanently changed to apartment J.
