Continuity mistake: In this episode, it shows Randall in Miss Grotke's class, but in every other episode, it's never shown him in there.
Continuity mistake: When Randall's dad is talking to the gang about what Randall has been telling him about them (when they are outside, in front of the bouncy thing), his moustache disappears mid-sentence (in a close-up of him) and reappears when he is shown again.
