Robert's Box

I’ve got enough to pay the fee
Can’t you see i’m awful sick?
I’ll pay you well to do the trick
Doctor where’s your magic box
There’s no one here to count the cost
Name your price and make the sale
There’s no-one here to tell the tale
Doctor please don’t lock your door
I’ve never troubled you before
Just a pinch to ease the pain
I’ll never trouble you again
