Ya gotta love this line.  It’s use is fairly common in both movies, and on television.  It’s usually is yelled out by a son, when a stepdad is imposing his will on him.

“You’re not my father!!!  You can’t tell me what to do.”

It’s the ultimate biting line, because the stepdad can never really come up with a good response.  The stepdad could be the greatest human being in the world, but once that rebellious teen points out that there are no biological ties existent, he wins.

Perhaps I should try to apply this line to other areas of my life.  Next time my boss goes to me, “Would you mind sending out an email to the staff telling them that I’m postponing the meeting?”

“No!  Don’t tell me what to do.  You’re not my real father!!!”
