The Hair-Brained Scheme - S5-E22
Trivia: Notice in this episode that Mike Brady is nowhere to be seen. That's because he quit the show due to artistic differences with the producer. His absence is explained as being away on a business trip. It also wound up being the unexpected series finale.
Trivia: Matt is played by Todd Lookinland, brother of Mike Lookinland (who plays Bobby). This explains why he has a very strong resemblance to Bobby.
Trivia: Although a toilet is never seen in the entire show, this episode came fairly close as in one scene we hear a toilet flushing during the argument between Peter and Bobby.
Trivia: Carol and her three daughters had a cat named Fluffy - who "disappeared" from the show after the first episode (honeymoon).
Trivia: Florance Henderson's hair style on the show was done on purpose. Few knew that since the 1950's she lost all hearing in both ears. The left hearing came back, but she had a hearing aid over her right ear.
Suggested correction: In the episode "A Fistful of Reasons" from Season 2, her hair was short and her ears fully showed (unless the hearing aid was so small it was BEHIND her ears).
The Hair-Brained Scheme - S5-E22
Trivia: When Bobby considers giving up trying to sell the hair tonic, Carol starts listing names of famous people who didn't quit. The last name she mentions is Carl Mahakian. Bobby says he never heard of him, and Carol says "Because he quit." Carl Mahakian was the show's post-production coordinator. (00:09:50)
Trivia: Among the girls at the slumber party are Florence Henderson's daughter Barbara ("Ruthie") and Robert Reed's daughter Carolyn ("Karen"). They interact briefly; during the game of Truth Or Dare, Ruthie is dared to go check on the boys and asks Karen to go with her. In addition, Hope Sherwood ("Jenny") is the daughter of executive producer Sherwood Schwartz.
Trivia: Frank Delfino - who plays one of the Kaplutians in Bobby's dream - utters the line "One small step for spacemen, one giant step for Kaplutians." The line was an ad-lib. (00:14:05)
Trivia: "Billy Garst" is frequently mentioned as being the most popular boy in Jan's class. Bill E. Garst was one of the editors on the show.
Trivia: Rita Wilson - who is now married to Tom Hanks - makes her acting debut, playing "Pat" in the cheerleading scenes. (00:18:35)
Trivia: The man on stage with the young girl is Frank De Vol, who composed the music for the Brady Bunch and many other shows. (00:16:50)
Trivia: During the ending credits, when showing the boys (with their real names), this is the only episode in all of season one where Barry Williams (Greg) looks to the side just before all the cast is shown together once again. In all other season one episodes, he continues looking straight ahead the whole time.
Trivia: This pilot episode "The Honeymoon" was filmed in 1968. The remaining episodes in season one were filmed starting in 1969. This would explain why the kids look much younger in this episode as opposed to the following episodes at the start of the series.
Trivia: Some episodes featured cast members or guest stars from Gilligan's Island (both created by Sherwood Schwartz). Jim Backus (Mr. Howell), Natalie Schaefer (Mrs. Howell), and Denny Miller (Duke the Surfer, Tongo the ape man) all appeared in at least one episode of the series.
Trivia: Both Chris Beaumont and Hope Sherwood (Sherwood Schwartz's daughter) played three different characters in various episodes throughout the series.
Trivia: Each of the actresses playing the three girls were re-cast in a future Brady-related sequel, TV show or movie. A different "Jan" in "The Brady Bunch Variety Hour" (1976), a different "Cindy" in "A Very Brady Christmas" (1988), and a different "Marcia" in "The Bradys" (1990). The only sequel to feature the original three actresses together was "The Brady Girls Get Married" (1981). The other six characters always contained the original cast for all of these.
Trivia: According to one single line in one episode, it's revealed that Alice worked for Mike Brady and his boys while the first Mrs. Brady was still alive, meaning Alice was the Brady's housekeeper during two Mrs. Brady eras.

Trivia: The storyline of Greg telling the two girls at the salon that Mrs. Brady is wearing a wig and is completely bald underneath is mentioned nearly 10 years later by Mr. Furley in a "Three's Company" episode. Furley though refers to the actress' name (Florence Henderson) by saying "Mrs. Henderson wears a wig... she's as bald as an eagle".
