- Colbert Bump: The comic strip's whole existence was only brought into public recognition when YouTuber Quinton Reviews decided to look for Gnorm Gnat strips. It was also featured by Super Eyepatch Wolf.
- Keep Circulating the Tapes: The strips were never circulated outside of a regional Indiana newspaper, only being unearthed in July 2019 by Quinton Reviews. Even so, Jim Davis hardly mentions the existence of this strip.
- Old Shame: To an even greater extent than Gnorm Gnat; while Davis is happy to mention and deprecate Gnorm Gnat when speaking about his past before Garfield, he almost never mentions Jon at all.
- Popularity Redo: A number of early Garfield strips are redone versions of Jon strips. Towards the end of Jon's run (by that point renamed Garfield), a few non-bug related strips of its predecessor Gnorm Gnat were also remade into Jon strips.
