A man goes to his seat on an airplane and finds a parrot in the seat next to him. Once in the air, the stewardess comes by, and when the man asks her for a coffee, the parrot squawks, "And get me a whiskey, you cow!"
The flustered stewardess brings back a whiskey for the parrot, but forgets the coffee. When the man points this out, the parrot immediately drains its glass and yells, "And get me another whiskey, you cow!"
The upset stewardess returns shortly with a whiskey for the parrot, but still no coffee. The man decides to try the parrot's approach: "I've asked you twice for a coffee, cow, now go and get it!"
Two burly stewards grab the man and the parrot, take them to the emergency exit and throw them out. As they eject from the plane, the parrot turns to the man and says, "You know, for someone who can't fly, you're a mouthy S.O.B.!"
