This is how to handle the situation:
Schedule an appointment with your professor(s), then walk into his office (shutting the door behind you) and grab his tie. Yank it down so hard that it chokes him and his head slams into his desk and say with your other fist clenched,
"You punk motherfucker - I'm not going to waste my time on this bullshit and you're going to give me an A as if we didn't have this little discussion, capiche?"
If he says anything other than "yes" then grab his stapler and pistol-whip him with it. Directly after this break into his home and hang his pets from his ceiling fan, but take one of the pets, behead it, and place its head on your professors' bed. Then write, "I see you" above his bed using his favorite pet's blood.
If the plan outlined above doesn't work, you just might have to play hardball.
