Do you feel that sinking feeling?
Did you pay your debt?
The only ride with no admission
Takes you down the oubliette.
If you find a foothold,
A ladder, or a prop,
Recall the oubliette,
and the ones who stood atop.

This is where I'll hang my head
To ponder all regret.
This is where you'll find me
Down in the oubliette.
Who knows how I got here?
I'll find an answer yet,
But without a ladder dropping down,
Thus wins the oubliette.

we fight their war for less, for more; for masters we decry
all the while hoping we might live before we die
and trade our sands for crumpled bands desperately we save
to sample trickled ambrosia with one foot in the grave
