Out from the night, from the mists steps a figure
No one really knows his name for sure
He stands at 6'6" head and shoulders
Pray he never comes knocking at your door.
Say that you once bought a heart or new corneas
But somehow never managed to square away your debts?
He won't bother to write or to phone you
He'll just rip the still-beating heart from your chest!
(REEEEEPOOOO MAAAAAAN)
Now you can run, you can hide, you can try to...
But he always has a way of finding you

And none of us are free from this horror
For many years ago, we all fell in debt
New body parts were needed to perfect our image
And until our debts are clear, we will live in fear of the--

A lot o' people don't realize what's really going on. They view life as a bunch o' unconnected incidents 'n things. They don't realize that there's this, like, lattice o' coincidence that lays on top o' everything. Give you an example; show you what I mean: suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
