Can You Tell That This Doctor Used To Be A School Teacher?

I've been experiencing hair loss lately.  Only twice before in my life has it ever been this bad.  Thus, today I had a doctor's appointment after school.
Now, I like this doctor; he actually reminds me of Max.  It's almost as if the doctor could be Max's long-lost cousin or something.  Anyway, he's got a great sense of humor.
Let me share:

Doctor: *going over medical updates before talking to me about current symptoms*  Let's see; we did blood work in the summer, right?
Me: Yes.
Doctor: Still taking Vitamin D?
Me: Yes.
Doctor: Do you have the paperwork to schedule a mammogram for this year?
Me: Yes, I'll do that.
Doctor: And you remember that you'll need to have a colonoscopy before too many years, right?
Me: *cringing* Yes, I guess.  But that'll have to be during a summer; it's too involved for --
Doctor: Look, there's no law that says you have to have one by a certain birthday, you know.  It's a colonoscopy; you don't have to get all anal about it. *winks*
Me: *bursts out laughing*
