Phil mentions that he at 17 was really close with his friend Stacy's mom, Mrs. Robinson. This references two fictional characters, both of whom are the objects of affection of their daughters boyfriends. 1. "Stacy's Mom" is song by the band Fountains of Wayne. 2. Mrs. Robinson is a character in the movie The Graduate (1967), and the song "Mrs. Robinson" by Simon & Garfunkel. This relates directly to the episode, where Haley, to spite her parents, is dating an older guy, Kenny.
In this episode, the character Kenny who is dating Haley, and is played by Jason Mantzoukas, sells designer jeans & keeps lots of jeans in his car. In season 6, episode 1 of the animated show Big Mouth, Jason Mantzoukas' character Jay has a car full of jeans.
The episode is inspired by the phrase of the same name.
