Proper Education/Another Brick in the Wall Lyrics

We don't need no education
We don't need no thought control
No dark sarcasm in the classroom
Teacher leave them kids alonePink Floyd - Proper Education/Another Brick in the Wall - http://motolyrics.com/pink-floyd/proper-education-another-brick-in-the-wall-lyrics.html
Hey! Teacher! Leave them kids alone!
All in all it's just another brick in the wall.
(All in all you're just) another brick in the wall
