George Cooper Sr. was also a health/PE teacher

I think Principal Petersen once mentioned about George being a health teacher, but we never actually saw him teach a class. When he's not in the field coaching his team, we usually just see him in their office or roaming around the hallway randomly bumping into Georgie or Sheldon. So it is easy to miss the fact that he was also a teacher just like Coach Wilkins.

During my first watch, I honestly didn't realize this. I thought he's just the school's football team coach and nothing else.
