I thought this whole story line in all the episodes that deal with Mrs. Carruthers obession with Joey was silly. It was clear that Joey had no interest in her but she acted silly the whole time making herself look foolish chasing after him.
Joey was stuck when he started teaching Michelle's class. Most of Michelle's friends know Joey as the funny guy. So while Joey was trying to be serious in his teaching he gets a lot of feed back from the kids. It was fun to see a relationship starting to grow between DJ and Viper.
