Everybody loves a clown, so why don't you?
Everybody laughs at the things I say and do
They all laugh when they see me comin'

But you don't laugh, you just go home runnin'
Everybody loves a clown, so why can't you?
A clown has feelings, too

I joke around at a party when you are there
But you don't laugh, you don't look, you just don't care
If you wonder why this clown is cryin'

Look a little closer, inside I'm dyin'

Very little modification needed, that song was creepy enough to begin with.
