Probably he last year teaching. Very cool guy, knows alot. Didn't teach his last year at all. Good times.
Doc is awesome... I still can't really tell if he's actually teaching or just writing, but I understand it all so it's all good. Funny guy.
I do have to agree that Doc is a very funny guy, but I can't follow what he says.
He is a funny teacher and if you have any questions he will help you. He's one of my favorite teachers.
