The Simpsons episode "Homer and Apu (#5.13)" guest stars James Woods with the joke that he is working at the Kwik-E-Mart because he was researching a role - like Michael J. Fox's character (Nick Lang) was in this movie which James Woods had a part in but as the opposite role.
In this episode James Woods also lists this movie as his previous work when interviewed to be employed by the Kwik-E-Mart.
Nick Lang: Ever killed anybody?
John Moss: Counting today?
Nick Lang: C'mon John. Look, my character kills this guy. It's probably an innocent by-stander. I just want to know what that's like.
John Moss: You can't. Not by asking someone.
Nick Lang: Will you open up? I just want to know what it feels like to be inside your skin.
John Moss: I DON'T WANT YOU INSIDE MY SKIN, YOU UNDERSTAND? It's private! What's in there belongs to me! You're not gonna learn what it means to be a cop by eating hot dogs and picking your teeth and asking stupid questions. We live this job. It's something we are, not something we do! Every time a cop walks up to a car and has to give a speeding ticket, he know he may have to kill someone or be killed himself. That's not something you step into by strapping on a rubber gun and riding around all day. You get to go back to your million dollar beach house and your bimbos and your blow jobs and you get 17 takes to get it right. We get one take. It lasts our whole lives. We mess it up and we're dead.
Nick Lang: [picking up a tape recorder] **** was that great! John. Look. Can you just say that one more time for me, please? John.
