Right, so Slip Case...

Lyrics:
You're my plastic Excalibur
Everything that I've ever waited for
Hidden in a slip case I bought at a dollar store
Worthless on the outside

You're my soon to be gallows
Ten feet high with aluminum scaffolding
Hidden in an alleyway, waiting to catch me off guard
I'll be cut loose

You're my poisonous pencil
I can't say what I want without feeling sick
Hidden under paper that I'm about to pick up
Worthless on the inside.

It's heavy.
