Trivia: In the scene where Greg is entering the drug store, listen to the lyrics of the music playing on the speakers - they are very similar to his speech when he says grace in the dinner table scene. Obviously where he got his words from, but not immediately obvious unless you listen for it.
Question: Pam, Greg, and Kevin appear to be in their late twenties or early thirties, but Pam says that the movie "Top Gun" was very popular when she was dating Kevin. "Top Gun" was released in 1986; more than ten years before this movie is taking place. Because Pam was engaged to Kevin at one point (she also describes their relationship as "more physical than anything else"), they must have been legal adults when they were together. Why would the movie "Top Gun" have been "very popular" while they were dating?
