This is the first time I've ever seen an implication that Jon went to work. What is his job?!
According to Wikipedia, which admits it's not clear what Jon's job is, it says that previously he was a cartoonist. Then in current strips it's unclear if he's still one because one strip says he works at a flute factory. And that in another comic, Garfield says that Jon has a Master's Degree in Special Education and that it's worthless.
Wikipedia also has a copy of this image for Jon Arbuckle. Seems as good an excuse to post in here as any. Am I the only one to think he's trying to impress the lady-types?
