Parasite

Out walking one night, I came to a crossroads, and it was there I taught the Devil to play guitar.

He was trying to hitch a ride but having no luck on account of the hooves.

I had no wheels, so instead gave him a tune. Little earworm it was, burrowed into his head and wouldn’t let go.

He said, “You know who I am?”

I said, “Son, I know who you were.”

So the Devil conjured himself some strings, sat at that crossroads and started to play.

“Pass it on,” I said.

Far as I know, he’s still there.
