Jawohl. LOL.
I was watching this movie in german a few years (BIG UNDERSTATEMENT) back, and this kid gets in trouble with the teacher. She says to him, "Brille ab!" ("Pardon me, but would you kindly remove your glasses?")
Then, she grabs the back of his head, and slams his face into the desk.
And THAT is why germans had the best engineers in the world.
