Roger says he co-wrote the movie City Slickers with Babaloo Mandel.
When Francine tells Stan that Roger shot Hayley, he replies: "So what? She shot me before, I've shot you a couple of times, everybody shoots everybody, it's how we communicate in this family." This is a nod to:
"Stannie Get Your Gun": Hayley shoots Stan in the neck, paralyzing him, under the impression that there were blanks in the gun.
"Haylias": Hayley shoots Stan when brainwashed; he is saved by doctors.
