the worth of one soul

A little bird once went around asking, "What would you trade your soul for?"

A tiny chick told the bird, "You don't have a soul." And the bird repeated its question. 

The chick said, "You lost yours a while ago." 

"What would you trade your soul for?" The bird asked. 

"You don't have one," the chick said, and left. 

"What would you trade your soul for?" The bird asked the empty air.
