I cannot describe how terrifyingly beautiful Sufjan Stevens' song John Wayne Gacy, Jr. is. 
Gacy is the infamous Chicago serial killer.
Pick up Sufjan's CD Illinois. You won't be sorry. And don't miss the last four lines of the song.
"John Wayne Gacy, Jr."
His father was a drinker
And his mother cried in bed
Folding John Wayne's T-shirts
When the swingset hit his head
The neighbors they adored him
For his humor and his conversation
Look underneath the house there
Find the few living things
Rotting fast in their sleep of the dead
Twenty-seven people, even more
They were boys with their cars, summer jobs
Oh my GodAre you one of them?
He dressed up like a clown for them
With his face paint white and red
And on his best behavior
In a dark room on the bed he kissed them all
He'd kill ten thousand people
With a sleight of his hand
Running far, running fast to the dead
He took of all their clothes for them
He put a cloth on their lips
Quiet hands, quiet kiss
On the mouthAnd in my best behavior
I am really just like him
Look beneath the floorboards
For the secrets I have hid
