The scene where Stewie is panicking and several different characters stand in line and take turns attempting to calm him down in bizarre ways is a reference to a scene from the movie Airplane!
It appears as though the female star of the adult film that Chris watches with his friends is seen later in the episode in the front row of the money management for drug dealers class that Peter teaches.
Jillian mistakenly calls Stewie "Stevie" over dinner, to which he replies "... it's STEWIE by the way". "Stevie" is the name given to him in the French version of the show.
In this episode they mock Liam Neeson playing a cowboy with an American accent, he later appears in Seth MacFarlane's A Million Ways to Die in the West (2014) as a cowboy but with an Irish accent instead.
Since Chris is 13 and underage he would technically be arrested for being in posession of pornography also he and his friends were likely breaking and entering as well as shoplifting all of which would land him in juvie until he turns 18.
