TF2 Mercenaries

Today was a normal day in your class. You are a student at college/school. Your teachers had to go away for advanced training, so the school invited TF2 mercenaries to replace teachers and teach your subjects. You were studying computer science when your homeroom teacher, who was also a life safety teacher named Mr. Richie, walked into the classroom.
Mr. Richie: Guys, meet your temporary teachers! Heavy is your new Russian Literature teacher, Medic is your Biology teacher, Spy is your French teacher, Sniper is your temporary shooting coach, Engineer is your Physics and Labor teacher, Scout is your Physical Education teacher, Pyro is your Drawing teacher, Demolitionist is your Chemistry teacher. Meet your teachers and treat them with respect. I hope you get along.
the day went on, the lessons continued
