Cody: [Holds up chocolate pudding.] I found your pudding.
Zack: Oh, thanks. But I could've sworn it was vanilla when I lost it.
Trivia: Maddy starts to film her movie and Mr. Mosby tells her that he is ready. Look at what he does right before she starts filming. He chants "Mah, mah, mah" and does the same thing Ashley Tisdale does in "High School Musical" before performing.
Question: What Happened to Muriel? Around season two she disappeared.
