The System as the Master Deceiver by Circle of Dead Children Lyrics

The instinctual, rear section of the brain has pushed its way forward and over
Animal over human, Instinct over intellect
Let your teeth rot 'till they drop out and the hairs upon the back of your neck stand tall and ridged
Universal brain altercation
Serotonin
Dopamine alteration
Sick as a dog, Rehab
