When Jimmy Cooper is talking about the ESPN Classic game he is watching to his wife, Julie, he claims that it is the 1986 NBA Finals Game 7, Lakers vs. Pistons. The audio says 1986, but his lips say 1988. His lips say the correct date, as the 1986 NBA Finals pitted the Boston Celtics against the Houston Rockets, and only went six games.
Jimmy says 1986 instead of 1988, due to an overdub. This was most likely changed due to the age of Marissa and 1986 lines up properly to Julie being pregnant with Marissa. Even though the ages of the characters are an ongoing continuity error.
During this episode, Jimmy Cooper explains to his wife that the out-of-season basketball game he is watching on ESPN Classic is the 1986 NBA Finals Game 7 between the Los Angeles Lakers and the Detroit Pistons - however, the 1986 Finals was contested between the Boston Celtics & the Houston Rockets.
