In the scene where Peter and Bobby are standing above the stage pouring water on Mike, dangling a rubber chicken, and throwing confetti, they are both wearing the shirts they wore when they were in the cave in the episode "The Tiki Caves".
The girl that's playing Muriel at the house where Peter and Bobby go to sell the tickets, is Karen Foulks. Chris Knight has another contact with the same actress on another episode in the season 2 episode, Will the Real Jan Brady Please Stand Up?. But on that episode, she played Margie Whipple at Lucy Winters' birthday party, a girl that Peter could NOT stand!
When Mike is reading his poem to the boys, they pretend to fall asleep. Bobby messed up his cue. After Greg puts his head on the pillow, Bobby starts to put his head down on Greg's shoulder but stops, waits for Peter, then takes his cue.
(Sam tried to guess who Alice's other man is)
Sam: Yeah, i see the way he looks at you when you thump his honeydews!
(The girls fool Sam into thinking Alice is seeing another man)
Sam: She doesn't even have the common decency to wait tl our love grows cold, before she's out glavanting with some nite-crawling rendevouzer!
Frank DeVol, the creator of The Brady Bunch theme song, played the horn playing father at the variety show. This was his only appearance on The Brady Bunch.
Carol while looking over lead sheets says the lyrics today make no sense. This is very inacurate as the in early 70s, and especially when this episode was shot the leading artist of the day were the Carpenters, Bread and Olivia Newton-John all soft rock acts.
The song "Together Wherever We Go" appears in the musical "Gypsy".
