Since a quick Google search turned up "Once More With Feeling" lyrics everywhere online, I am assuming that Mutant Enemy is as permissive with such things as they are with fanfic.

This has been going through my head since I first watched Episode II. (I'm not sure why there's a huge blank space between this paragraph and the table.)

DR. HORRIBLE	PENNY
Any dolt with half a brain Can see that humankind has gone insane To the point that I don't know If I'll upset the status quo If I throw poison into the water main   Listen close to everybody's heart And hear that breaking sound Hopes and dreams are shattering apart And crashing to the ground   I can not believe my eyes How the world's full of filth and lies But it's plain to see Evil inside of me Is on the rise.
	Look around We're living with the lost and found Just when you feel you've almost drowned You find yourself on solid ground   And you believe there's good in everybody's heart Keep it safe and sound With hope, you can do your part To turn a life around   I can not believe my eyes Is the world finally growing wise? 'Cause it seems to me Some kind of harmony Is on the rise
Anyone with half a brain Could spend their whole life howling in pain 'Cause the dark is everywhere And Penny doesn't seem to care That soon the dark in me is all that will remain   Listen close to everybody's heart And hear that breaking sound Hopes and dreams are shattering apart And crashing to the ground   I can not believe my eyes How the world's full of filth and lies But it's plain to see Evil inside of me Is on the rise.	Take it slow He looks at me and seems to know The things that I'm          afraid to show And suddenly I feel this glow   And I believe there's good in everybody's heart Keep it safe and sound With hope, you can do your part To turn a life around   I can not believe my eyes Has the world finally become wise? And it's plain to see Rapture inside of me Is on the rise
