"We Don't Need No Education", with an assembly line of kids institutionalised into robots, all wearing anonymous, scary masks and falling into a grinder out of which meat exits. The production values impressed me very much, and the theme held resonance.
I can't fucking stand the education system.
Great sequence, though my personal favorite sequence might have to be the Fascist power-dream hallucination sequences tied to the tunes "In The Flesh", "Run Like Hell", and "Waiting For the Worms."
