During the scene when Marcia is in the kitchen trying to eat spaghetti: when the camera starts to pan out, look carefully at Carol, who is in the background behind the counter. You can clearly see that she is looking up at the director to give her her cue after the camera fully pulls out. She's holding a dish towel and silverware, waiting. As soon as the camera stops moving, you can see where she gets her cue, because she suddenly gets a big smile on her face and busily begins to wipe the silverware and say her line.
Marcia's date in this episode is named Alan. The press, however, wrote it down as Craig.
This episode gave the usually sunny and happy Marcia Brady some intense crying scenes. Actress Maureen McCormick has admitted that although her castmates didn't know it at the time, all her tears were real, because she was going through a lot of emotional trauma at home. Shortly before the episode was filmed, McCormick's parents had gotten into a horrible fight, and her father admitted to having an affair with a family friend. McCormick claims that she "summoned the tears easily" for this and any other episode that required her to get upset, and they were actually some of her favorite scenes, because with the difficult home life she had, it was a good release for her.
In the scene with Cindy and Marcia in the bathroom, Marcia's braces are gone! If you look closely, they have slid up to the top of her teeth and are on her gums. This happens several other times in this episode.
Look closely and you'll notice that there's no glass in the sliding glass doors at the Brady house.
In the scene with Cindy and Marcia in the bathroom, you can tell that the amount of facial cream on Marcia keeps changing between shots.
Marcia: Well, some people say things just to be nice.
Jan: Would we say things to you just to be nice?
Bobby: We're your brother and sister.
Marcia: Then you didn't really mean it.
Alice: Of course they meant it.
Marcia: I wonder if I can ever believe what anyone in this family says to me ever again, at all!
Jan: Honest, it's a real pretty dress!
Bobby: Even if it doesn't cover up your braces.
Marcia: Tell me the honest truth. Do I look funny?
Cindy: Of course not, Marcia. You look beautiful.
Jan: Thanks, Cindy!
Cindy: But how do you get the toothpaste through all that barbed wire?
Jan: (when Cindy is about to go into the bathroom) Marcia's in there.
Cindy: Daddy said to act natural--and I always barge in on Marcia when she's in the bathroom!
Alan: I can't take you to the dance.
Marcia: Why not?
Alan: Well, my parents are going out of town.
Marcia: So what?
Alan: I have to go with them.
Marcia: I don't believe you. You just don't want to be seen with a girl who has braces, like I do now. I hate you, Alan Anthony. I hate EVERYBODY!
This is the only episode that Marcia is seen wearing braces.
Peter and Greg are the only Brady kids that never get braces.
Viewers familiar with The Brady Bunch would see the situation - involving family members unknowingly (and separately) asking three different boys to go to a school dance with the dateless, luckless pre-teen daughter - on Family Matters (incidentally, the first episode to feature Steve Urkel). Like the sitaution on Family Matters (involving Laura) attempts by Mike, Greg and Alice to find a date for Marcia go wrong.
In this episode, Marcia's braces are on. Then, next they are off. Then they're on. It goes on the whole episode
