The show is known for having a scattered time line with tons of plot holes. For example, in this episode, they are celebrating Valentine's Day. In the previous episode, which was supposed to have happened the day before, Red tells Kitty's parents he will "see them at Christmas".
Hyde wears an International Paper t-shirt throughout most of the episode.
Eric references Star Wars, saying that he and Donna are going to "use the Dark Side to [their] advantage". However, the concept of the Force having a Light Side and a Dark Side wasn't introduced until The Empire Strikes Back in 1980, more than two years after this episode takes place.
The Dark Side was mentioned in the first Star Wars movie when Obi-Wan telling Luke what "happened" to his father says Vader was seduced by the Dark Side of the Force.
