Sheldon Allan Silverstein - For Sale

One sister for sale!
One sister for sale!
One crying and spying young sister for sale!
I’m really not kidding,
So who’ll start the bidding?
Do I hear the dollar?
A nickel?
A penny?
Oh, isn’t there, isn’t there, isn’t there any
One kid that will buy this old sister for sale,
This crying and spying young sister for sale?
