Replying to Evan Raps and Nick Mercon's song in Ski Movie 2.

Does anyone know who sings it or what it's called?

I write messages on money.
It's my own form of social protest.
A letter printed on paper that no one will destroy, passed indiscriminately across race, class and gender lines, and written in the blood that keeps the beast alive.
A quiet little hijacking on the way to the check-out counter.
And a federal crime.
I hope that someone will find my message one day when they really need it, like I do.
'You are not a slave'
