Even though the house used in the pilot is clearly a single story, when Mike and Carol go back to pick up the boys, Carol tells them that Marcia, Jan, and Cindy are "waiting downstairs."
The shirts that the boys wear in the opening credits are the same ones they are shown wearing in the first scene at the breakfast table.
If anyone wonders why Cindy's hairstyle here as pigtails is so much like that of Buffy Davis played by Anissa Jones in the 1966 TV sitcom Family Affair, or vice versa, it's because Cindy copied off of Buffy.
Tiger couldn't have opened the window with the automatic switch because the car is not running!
The most unbelievable part of this episode is Mike and Carol coming back to the house to bring all of the kids on their honeymoon.
Fans of another 70's TV show may recognize the minister who marries Mike and Carol: that's actor Dabbs Greer, who played the Reverend Alden for ten seasons on "Little House on the Prairie". 21 years after this episode Mr Greer would return to play the same part as the minister who marries Bobby to his college sweetheart in the pilot episode of the 1990 reunion show The Bradys.
This is the only episode that shows the girls' cat, Fluffy.
If Carol's first husband had the last name of Martin, then Marcia's birth name must have been Marcia Martin.
Towards the end of the wedding they show a seen where Tiger the dog is chasing Fluffy the cat across several tables with refreshments and food for the wedding reception. If you look closely you can see strings attached to the tables to cause them to shake in order for the cake and plates to fall off.
This is the only episode in which Mike and his boys talk about the boys' mother. Throughout the rest of the series, they never talk about her.
While Tiger is in the car, you can see a close-up of his paws near a manual window-opening device. Yet later, when Tiger tries to escape from the same car, his paws are shown pressing against an automatic window opener.
After Mike and Carol confess to each other in the den that neither of them wrote the letter, they decide to let the kids know after they finish the program they're watching on tv. In the next scene, the entire Brady family is watching television in the living room - presumably they are watching the same program the parents referred to. Yet, Mike and Carol are wearing different clothing. Carol is wearing an entirely different dress, while Mike changed from jeans and a red shirt to dress slacks, shirt and tie.
The names of the kids and Alice when they wrote to Dear Libby are:
Cindy: Kitty Karry-All
Bobby: Feeling Awful
Marcia: Desperately Worried
Peter: Down In the Mouth
Jan: Real Frantic
Greg: Guilt Complex
Alice: Innocent Bystander
In this episode, Mike reveals that he was in the school drama club.
If the children went through the trouble of putting on a second performance so the entire Brady family could attend, why not allow all the other empty seats to be occupied by other children's family members who could not attend? Furthermore, if the point was to make a special exception for Cindy, then why not allow enough seats for all her family to attend the original performance? Certainly, there were a few extra seats at that performance.
The very premise of there only being enough seating for "one person from each student's family" to attend the school play and concert is ridiculous. There are 86 students appearing in the performance; even if every child could invite both parents, what school auditorium only holds 172 people? And a panoramic shot of the auditorium at the beginning of the episode clearly shows plenty of seating. Failing that, why not just put on the play twice?
Cindy wears Marcia's wings.
In this episode, Greg comes home and needs math help. He tells Alice that he'll go to mom because "she's a wiz at this stuff". Yet, in "Father of the Year", when Marcia needs help with her homework, she needs to rely on dad instead of mom because "it's math" with the implication being that mom is no good at math.
Correction: the account of the episode listed above was actually for the episode Father of the Year
In this episode we learn from Alice that Mike, Greg and Peter have had Tiger longer than they've had Bobby.
The boxes the boys take from the master bedroom are not the same boxes they are shown carrying into the girls' room.
