This episode is out of sequence with the other episodes in the season, as Miss Slovak quit teaching to pursue a career in professional golf, as referenced in the first episode, "New Teacher". But she is once again their teacher here with no sign of Mr. Simmons.
During the "Hookey" episode, Arnold and Gerald are sitting on a curb, eating ice cream, while in disguises. The curb has the words "LOADING ZONE" written on it. After two cops mistake them for crooks, and begin to haul them away, the curb now says "LOAING ZONE".
