"Excellent Service" joke

A man bought a parrot, and for 20 years the bird kept silent, never uttering so much as a word. Every morning the parrot would wake up, stand patiently on its perch, and wait for its owner to come and feed it.

One morning, the man overslept. Using its beak, the parrot pried the cage door open, flew out, and perched on the man's head.

Pecking its owner's nose, the parrot squawked and said, "Excuse me, but it's nearly noon and I'm starved."

The man sat bolt upright, "Polly, you can talk!"

"Of course, I can talk," said the parrot.

"Then why haven't you said anything for 20 years?" asked the man excitedly.

"Because up till now", screeched the bird, "the service has been excellent!"
