I bought a piano.
But it was haunted.
The ghost of a little girl played it at night.
And played it badly.
I hired the ghost of a piano teacher to give her lessons.
She got better, but the piano was out of tune.
So, I hired the ghost of a piano tuner to tune the piano.
“You need a living piano tuner,” said the ghost.
And he billed me for his time.
I refused to pay the bill.
The ghost of a collection agent kept calling me, over and over.
I hired an exorcist, and sold the damn piano.
