Let me introduce myself I'm a social disease

I've come for your wealth leave you on your knees

No time for feeling sorry, I got here on my own

I won't ask for mercy, I choose to walk alone

What's yours is mine and what's mine is mine too

If you shake my hand better count your fingers

What if I do get caught? What if there is no judgment?

If I'm right I lose nothing, if you're right I lose it all

I ought to get caught because I'm doing something wicked

I'm guilty haunted by my fear and the only consequences

Are Dread and the Fugitive Mind

You built walls to protect you so no one will infect you

Pursued by those out there that vanish in thin air

Come a long way to find what you really left behind

You don't know when the end is but it's coming fast

What's yours is mine and what's mine is mine too

If you shake my hand better count your fingers

What if I do get caught? What if there is no judgment?

If I'm right I lose nothing, if you're right I lose it all

I ought to get caught because I'm doing something wicked

I'm guilty haunted by my fear and the only consequences

Are Dread and the Fugitive Mind
