- Arnold can imitate his grandfather's voice remarkably well.
- Principal Wartz played hockey in the past, and had a chance to go pro if it were not for an accident in which he lost his toe in a wheat thresher.
- When Arnold and Gerald are in House of Costumes, Gerald comments about being a "free man in Paris, unfettered and alive," and that he heard it on a hippie record. That album is Joni Mitchell's 1974 album "Court and Spark." The song he is quoting is "Free Man in Paris."
- The episode's title is misspelled on the Hey Arnold! The Complete Series DVD as "Hooky". However, the word can be spelled either way.
