Rape scene
In the most recent episode of American Dad! there was a reference to RotN...
Steve: Yeah. We nerds have a long history of making our dream girls fall for us. Like that kid in Revenge of the Nerds who finally won the heart of that cheerleader.
Barry: Oh, you mean the one who put on a Darth Vader mask so he could rape her at that carnival?
Steve: Yep
Snot: Nah, never saw it
Of course, the inside joke is that Snot is voiced by Curtis Armstrong, who played Booger in RotN.
