Courteous Parrot?

A lady is walking down the street to work and sees a parrot in a pet store. She stops to admire the bird. The parrot says to her, "Hey lady, you are really ugly." Well, the lady is furious! She storms past the store to her work. On the way home she saw the same parrot in the window and the parrot upon seeing her says, "Hey lady, you are really ugly." She was incredibly ticked now. The next day on the way to work she saw the same parrot and once again it said, "Hey lady, you are really ugly." The lady was so furious that she stormed into the store and threatened to sue the store and have the bird killed. The store manager apologized profusely and promised the bird wouldn't say it again. The next day, when the lady walked past the store after work the parrot said to her, "Hey lady." She paused, scowled with an icy and deadly stare, and said with a hoarse voice, "Yes?" The bird, strutting back and forth on its perch in a cocky manner, said, "You know."
