Pet Store Parrots

A guy walks into a pet store wanting a parrot. The store clerk shows him two beautiful ones out on the floor.

- This one's $5,000 and the other is $10,000. - the clerk said.

- Wow! What does the $5,000 one do?

- This parrot can sing every aria Mozart ever wrote.

- And the other? - said the customer.

- This one can sing Wagner's entire Ring cycle. There's another one in the back room for $30,000.

- Holy moly! What does that one do?

- Nothing that I can tell, but the other two parrots call him 'Maestro'.
