This episode is parodied in A Very Brady Sequel 1996.
Kathy Lawrence was in "The Personality Kid" in which she and Marcia were friends. In this episode, it's mentioned that Kathy beats Marcia in cheerleading but it's not revealed whether she won honestly or not or if they still stay as friends.
Peter throws left-handed.
This is the first of two Brady Bunch episodes that refer to Benedict Arnold. In Everyone Can't Be George Washington, which aired 14 months later, Peter played the role of Benedict Arnold in a school play.
It's unclear how the Bradys were suppose to lug a heavy dunking booth like that down to the school, even without the water!
Peter: When are you going to grow up?
Bobby: When I get older.
(Greg, about Warren)
Greg: He's at the top of my crumb list...in fact, he's at the bottom of my crumb list, too and he's every crumb in between!
Mike: (to Greg) Did you see Kathy because you really wanted to, or was she just the best thorn you could find to stick in Marcia's side?
(After Greg disobeys)
Mike: Hi, son. I think we need to have another talk.
Mike: Marcia has the right to see any boy or girl she wants to. Okay?
Greg: Okay. (sunddenly antsy) Would that right apply to anyone else in this family?
Carol: There are no special rules just for Marcia.
Greg: (very pleased gets up/leaves for school) Thanks Dad.
Carol: Well, what was that turn around all about?
Alice: ...and they said 'So-long" and I said 'Far out'! I didn't want them to think I wasn't 'on-it'!
Kathy: F-F, F-I-L! L-L, L-M-O! O-O, O-R-E! Fillmore Jr. High! Yey, team!
