Corrected entry: When the Gang is going to Palm Springs over President's day weekend early in the series, Kelly and Donna tell Brenda she's the last virgin. This implies that Donna is not a virgin, however, after she starts dating David, all of a sudden she IS a virgin and wants to wait until she's married.

Emily Valentine: This isn't Beverly Hills! It's Knot's Landing.
Trivia: James Eckhouse plays Jim Walsh, father of Brandon Walsh (Jason Priestley). In real life, Eckhouse is only 14 years older than Priestley.
Question: In the first few episodes, the Walshes live in a different house than the one they live in throughout the series. Nothing was ever even mentioned, I don't think. Was it a mistake, or did I miss the explanation?
Answer: There was no explanation. Usually, when a show doesn't know if it's going to be picked up or not, they will use stock footage until they can spend the money on a real location.
Correction: Donna may not have wanted to seem 'uncool' by admitting that she's a virgin. It wasn't until she started dating David that it became an issue, and she had to make a stand against it.
