So the musician goes past the pet store, on his way to a gig. He hears a voice singing so beautifully, like Ella Fitzgerald. He looks inside the pet store, and lo and behold, it is a parrot, with exotic, lush plumage, all green, red and yellow, scatting like Ella Fitzgerald. The musician (who was a jazz player) is blown away. He asks the owner, “How much”? The owner says “$20″. The musician figures that’s cheap, so he says, “Sold!” The pet store owner says, “There’s only one hitch. You’ve got to buy her mate.” The musician says “Where is he?” The pet shop owner says “We keep him in the back.” The two men go into the back room, and there on a perch is a one eyed, one legged, half de feathered parrot. The bird looks surly, and when the men approach, he tries to nip their fingers. The musician says, “Normally, I wouldn’t be interested, but if they’re a pair, I guess I’ll take him too. Anything to have that parrot that sings like Ella Fitzgerald”. The pet shop owner says, “That’ll be $500 for him.” The musician is peeved. ”What are you talking about? The other bird is beautiful, all green and yellow, and can scat like Ella. You said $20 for her. This one has hardly any feathers, a bad disposition, one leg, one eye, and tried to bite me. How can you charge $500 for him?” The shop owner looked the musician in the eye and shrugged. ”HE’s her arranger.”
