Adam Sandler makes a cameo as himself chaperoning the school dance. However, as Luke talks to him, he says, "If we have to have grown-ups, too, I'm glad it's you." Luke plays the son of Sandler's character in Grown Ups and Grown Ups 2.
The title is a reference to Adam Sandler's film Punch Drunk Love.
One reference to the Grown-Ups films is that Adam Sandler says he made the punch he brought in Kevin James's bathtub. Actor Kevin James co-starred with Adam Sandler on various movies, including Grown Ups & Grown Ups which Cameron played Sandler's son.
As a promotional stunt for Grown-Ups 2, they worked the title into the script of the episode to promote the movie, which also starred Cameron Boyce as Adam Sandler's son
