Character mistake: At one point Cory is telling Shawn about how he can't protect Topanga and they've only been married for one week. But they spent their wedding night in jail, 12 days on their honeymoon and 1 night in their new apartment. So actually the couple have been married for 2 weeks.
Continuity mistake: At the start, in Cory and Topanga's dorm room, Topanga asks if Cory thinks she is attractive. He says "Yah, let me prove it," and leans on his side. For a split second they show Topanga walking to the door. Then it shows Cory and he is sitting up, if you pay close attention, to Cory and the way he sounds, you can tell they had to start over because somebody messed up
Plot hole: At the beginning of the episode, Eric and Jack call the cops on Luther for planning an illegal rave at the college, but the cops let him go because he had not started the rave. He still broke into the student union building, and therefore should have still been arrested. (00:00:20 - 00:02:10)Phaneron
Continuity mistake: When the show starts, Angela and Shawn are kissing. The shot changes to Topanga and Cory, who has popcorn on his shirt. The shot goes back to Shawn and Angela, when Cory is shown again, the popcorn is gone. Again the shot changes to Shawn and Angela, then back to Cory and the popcorn reappears.JuliaD
Revealing mistake: When Eric tells Cory and Shawn that the hot chocolates were $4, Cory looks up at the prices and says "that's the retail price." As the scene and the rest of the episode go on, if you pay close attention to the sign that has all the prices, hot chocolate is not an item.JuliaD
Continuity mistake: In the season 7 episode "I'm Gonna Be Like You, Dad" Alan and Amy's youngest son Joshua is shown to be an infant. However in this episode, which takes place roughly 4 months after the aforementioned episode, he is shown to be around 2 years old.Phaneron
