As Cindy exits the kitchen, she sticks out her tongue for a brief second. Susan Olsen thought they were doing a rehearsal and didn't know that it was the real thing.
At the end of the episode, when Alice wakes up the family to do calisthetics, after the entire family gets to the top of the stairs, Mike says "Alice, it's 6:00 in the morning". Yet there is a brief gap of silence between "the" and "morning", and Mike's mouth is still moving. It's an urban legend that he swore and that they bleeped it out. Of course, this is unrealistic, as no one else in the scene is seen reacting, as they would have if he really had sworn. The reality is thet there was some kind of editing glitch or dubbing error that caused the audio to momentarily fall out of synch with the video. To confirm this, mute the sound altogether while reciting Mike's dialogue yourself, and you will see that he only says "Alice, it's 6:00 in the morning".
Mike's nickname at Fremont High School was "Hot Lips."
The name of the Mike's old alma mater is Fremont High School.
The name of Mike's ex-girlfriend from high school is Irene "Bobo" Hessleraugh.
Aunt Jenny addresses her chauffeur as "Sam," marking a rare event where two characters on the same series have the same name. Alice's boyfriend is also named Sam.
Aunt Jenny has met Wilt Chamberlain, Harry Houdini, Pietro, Golda Meir, Indira Ghandi, the King of Siam, Madame Kruschev, and has an appointment to meet Georges Pompidou. She was also invited to a birthday party on Ari's yacht, referring to Aristotle Onassis and she likes his wife, Jackie Kennedy Onassis, widow of slain president John Fitzgerald Kennedy.
In the ending scenes after they recorded the song, Greg says that he didn't want Peter to talk because they were saving Peter's voice, and Alice says "To record Greg's Song", but they had already recorded it.
When Peter is singing that's not really his voice squeaking - it's a production assistant.
In "The Winner" from the previous seaon, Carol said Bobby was 4'3". in this season, Bobby was 4'8". Therefore, he grew 5 inches in one year.
Sam said if Bobby grew 6 inches a year until he was 21, he'd end up 10"2'. If Bobby was 10 at the time, he was 4"8'. That is normal size for a boy that age.
The boy Sam hired before Greg wanted 3 filet mignons as fringe benefits in addition to his $1.50 wages. Assuming the far outdated value of $5 per filet, the boy was asking for 10 hours wages as fringe benefits.
Bobby hangs from a crossbar in hopes that gravity would force him to grow. Even if that plan had merit, only his arms would have lengthened. His head to foot height would have remained static.
When Greg and Mr. Brady are waxing Greg's surfboard, Bobby comes and tells them one of his brainpower facts. He says that the Ob is the fourth longest river in the world. I guess Bobby didn't study hard enough because the Ob is actually the sixth longest in the world, not the fourth. The fourth longest river in the world is the Mississippi-Missouri.
Marcia and Jan are wearing the same dresses that they wore for the family photo in "The Not-So-Rose-Colored Glasses."
When watching TV with Bobby, Cindy mentions the "Kartoon King" show, the same show that Bobby appeared on in an ice cream-eating contest in the season 2 episode "The Winner."
The actor playing the photographer also played a photographer in "Tell It Like It Is," the year before.
In the final scene, Jan, Peter, Cindy, and Bobby sing the Davy Jones song "Girl" in the Brady living room and they are very loud and off-key. They obviously improve their talents considerably by the episodes "Dough Re Mi" (also Season 3) and "Amateur Nite" (Season 4).
On "Pop-Up Brady" they counted at least 37 times that they said Davy Jones.
Carol is upset about Greg making the football team, fearing he'll get hurt.Â She even says no son of hers is going to play that game.Â However, Peter was on a football team in the season 2 episode, "The Drummer Boy".
