"Don't Imitate Parrots" joke

On reaching his plane seat a man is surprised to see a parrot strapped in next to him. He asks the
stewardess for a coffee where upon the parrot squawks, "And get me a whiskey you cow!"
The stewardess, flustered, brings back a whiskey for the parrot and forgets the coffee. When this
omission is pointed out to her the parrot drains its glass and bawls "and get me another whiskey you
dumb".
Quite upset, the girl comes back shaking with another whiskey but still no coffee. Unaccustomed to
such slackness the man tries the parrot's approach. "I've asked you twice for a coffee, go and get it
now you stupid."
The next moment, both he and the parrot have been wrenched up and thrown out of the emergency exit by
two burly stewards.
Plunging downwards the parrot turns to him and says, "For someone who can't fly you're a brave stupid
dumb cow!"
