As in a trance , she follows the sound of the song and sure enough, there in a cage is this cheerful songbird happily singing her little heart out. A sign read "One-thousand dollars for the pair."

She looked deeper into the cage and way in the back she saw this other haggard bird with it's head down and he shaking his head left to right. The clerk came over and the woman said,"How much for just the songbird?"

The clerk said,"I'm sorry, you'll have to buy the pair."

The woman said, "But that other bird is so haggard and looks so depressed and he's hanging his head and shaking it back and forth, and this bird is so happy and singing so beautifully . Why do I have to buy that other bird?"

And the clerk said,"Because he's the arranger.
