The dead man teach me teach me so well said a river's in Heaven no river in Hell and when I croak to Hell I go with my dried up soul.
Then he add a complication: God love me so much he moved Heaven's river with a wooden cross now the river flow to my dried up soul so to Heaven I go. Oh, and I want it so.
Then he add a complication: I can say no. Don't want your river. Want to hop on the shore. So to Hell I go, with my dried-up soul just like before.
Then he add a complication: I can say yes. Put me in the river but only up to my chest. Don't dunk my head! So there's a little bit of no in my great big yes and I wonder what happens next.
When I get to Heaven and my head ain't wet God gonna say, “Woah, can't come in yet, I'm a burning sun, you're a little frog, I'll burn you up.”
And that's the reason for ghosts.
