Other mistake: When Mike is talking to Mr. Crawford and the operator asks him to deposit another 10 cents, Mr. Crawford said, 'Did I hear an operator ask for 10 cents?' Only Mike would have heard that recording, not Mr. Crawford (he didn't have the pay phone).

Starring: Robert Reed, Florence Henderson, Maureen McCormick, Ann B. Davis
Audio problem: At the end of the show when Alice is blowing the whistle, the whole family comes to the top of the stairs. Mike says "Alice, it's 6 o'clock in the morning" Watch his mouth. It looks as though he curses and the (curse) word was dubbed out.
Bobby Brady: Mom always says not to play ball in the house.
Trivia: Barry Williams has a Band-Aid on his lip in this episode because he was in a car accident a few days before filming and needed stitches in his lip. (00:05:00)
Question: Would someone please explain to me why Marcia did not just simply remove her dangly bracelet that endangered the girls standing in the house of cards competition after Carol said "Oh Marcia, Marcia, your bracelet"? It would have made it less stressful on her not to mention her team, and she wouldn't have had to restrain it with her other hand.
Answer: There were several episodes throughout the run of the show where Marcia was infatuated with a guy she went to school with. This bracelet could have been a gift from her then-boyfriend; as such, she would not want to take it off, as a sign of loyalty. A stupid thing to do, of course, but it's not a mistake for a character simply to be dumb.
Answer: The dangling bracelet was used for dramatic purposes - to keep the audience on edge.
