A burglar breaks into a house during the night knowing that the owners are absent and, as he is surveying what items might be pinched, he hears a voice saying, “Stop that or I will set the dog on you”.
Worried, he probes the darkness with his torch and finally notices in the corner a parrot in a cage. The parrot says again, “Stop that or I will set the dog on you”.
The burglar, amused, asks the parrot, “And what is your name, Polly?”
Offended, the parrot replies, “Don’t be stupid. I’m a boy and my name is Beverley”.
“Oh,” says the burglar, “And what sort of idiot names a male parrot Beverley?”
“The sort of idiot who calls his bitch rottweiler/Russian wolfhound cross Harold. Get him Harold”.
