(Your nervous system, your nervous system)
(Underground medicine, underground medicine)

A spark inside

(Traverse up my hide)
And when it clicks
There's no resist

Every time I hear a new baby cry
I thank my spark inside

And you get underground medicine
Underground medicine
I'm but a nervous system
Underground medicine

I found a reason not to die
A reason for the ride
The spark inside
When it hits the mind you get
Underground medicine
Underground medicine
I'm but a nervous system
Underground medicine
I had a psychosomatic voice
And one time it might come back

Underground medicine
Underground medicine
I'm but a nervous system
Underground medicine

On my pants I spilled expectorant
And the colonel shot better with 30 pints
They took his cup away
Take it away, take it away
(Used to 'ground) medicine
(Used to 'ground) medicine
