Gym Instructor
The Gym Instructor is a P.E. teacher at Calvin's school who appeared in a single weekday strip. He appeared as a fat, stout man with a crew cut and double chin wearing a T-shirt that read "Gym Instructor". It is unknown whether he worked alongside Mr. Lockjaw or if the latter replaced him. He told Calvin to get on the chinup bar. Template:-
