This episode marks the first time the "Whoa, Bundy!" cheer is shown.
Just before Kelly arrives at the bowling alley, a hand is shown, marking the scoresheet. Peggy's and Kelly's scores are the only Bundy scores that are actually legitimate. Steve's, Bud's and Al's scores all contain math errors.
The episode title is a reference to "Valley of the Dolls", the 1967 film adapted from the 1966 Jacqueline Susann novel of the same name.
