Background trivia and Production information for this entire episode guide for "My Three Sons" was Written by Geoff Brown, Editor.
Series star Fred MacMurray occasionally excercised his top billing power (and half ownership in show) by trying to shape the scripts which were more often than not, already written well in advance.
For this episode, Production Manager John Stephens recalls that in any given episode according to Fred, everything had to be completely accurate (read: believable) or he did not want to do it. In one particular scene in this episode, Mike's girlfriend is enamored of his father Steve. The next day in his office, Steve gets a phone call from this girl. Immediately MacMurray halted filming and said "Get John Stephens down here!" MacMurray explained that it would not be plausible to have the girl call Steve at the office - how would she know the number or even where he worked for that matter? Production Manager Stephens had to fully explain the logic behind this plot development. It is assumed that because he isn't at the studio for every scene being filmed, the girl would simply have asked Mike where her father worked. It usually satisfied Fred MacMurray if a logical explanation was provided to him. He felt this way because if a scene had no logic for the story to build to, then the show would ultimately lose credibility with the audience if they felt that they were somehow being manipulated.
The current release print of this episode lists the wrong writer and guest cast. Shirl Gordon is listed on the end credits as writer but this is lifted from an episode titled "Daughter for a Day" which also lists the guest cast from that episode. The correct scribes for this episode are Austn Kalish and Elroy Schwartz.
The music for this episode was scored by Arthur Morton.
This episode may well mark the first "appearance" of Sally Ann Morrison, when Bub references her name, mistakenly thinking that Mike is talking to her on the phone.
As in Episode # 57 from the second season when he was lecturing Robbie, ex-thespian Bub reminds Chip with the same line that "There are no small parts, just small actors!"
In one of his earliest roles, (and the first of two different M3S characters) we see a young, pre-Star Trek's Sulu, George Takei.
Future BIG star alert: A young Martin Sheen!
This is the second of three guest-star roles, as three different characters, on the series for Tina Cole:
1. Ina - House for Sale - 133. Season: 4 Episode: 22 2. Sherry - The Coffee House Set - 158. Season: 5 Episode: 10 3. Joanne - Robbie and The Little Stranger - 206. Season: 6 Episode: 22
Two seasons after that third appearance, Tina joins the regular cast as Robbie's wife Katie Miller Douglas
Here is the full text of the invitation, the British spelling of 'honour' consistent with Sally's English father:
Mr. and Mrs. Charles Frazier Morrison
request the honour of your presence
at the marriage of their daughter
Miss Sally Ann Morrison
Mr. Michael Douglas
at Bryant Park Community Church
on Thursday, the sixteenth of September

When Ernie and Uncle Charley initially attend the rehearsals for the show at the school, the opening footage shows the backs of the audience members -- but this is actually a duplicated shot from later in the episode during the the final performance. It's easy to spot in reverse as the extras filmed during this scene are wearing different clothes -- firstly suits and then casual attire. Perhaps the show's film editor needed some establishing shots and chose it from the earlier part of the episode hoping no one would notice?
This is George Takei's third appearance on the show (first in color).
Margie claims to a secretary out at the Aircraft Plant where Steve works and that she is just 22 years of age.
The actual name of Margie Milford's fiancee is Jim Johnson. Steve mentions that he has been working in Bolivia on a government project.
Oldest son Mike is mentioned in this episode. His college diploma hangs on the wall in Chip and Ernie's bedroom.
Guest star Betty Lynn is best known to TV audiences as Thelma Lou, the girlfriend of Barney Fife, on The Andy Griffith Show which was also produced in the 1960s.
The pennants hanging on the wall in Robbie and Katie's bedroom are for Michigan and Washington.
In an earlier offering, Robbie was the one being watched in the similarly titled episode 'The Chaperone' from Season 4. (Bub was his chaperone in that one.)
