Bloke buys a Cockney Parrot but gets sick of it saying, "I'm from London and I'm hard as f**k!" so he puts a Kestrel in its cage. Next morning, he finds the Kestrel dead and the Parrot says, "I'm from London and I'm hard as f**k!" so the bloke puts a Golden Eagle in the cage. Next morning he finds the Eagle dead and the Parrot with no feathers! As he looks in the cage, the Parrot says, "Had to take me coat off for that f****r!"
