A Londoner Is Walking His Dog...

...When he passes a policeman. As he walks past, the dog leaps up and bites the copper's hat off, and tears it to pieces.

"Oi!" the policeman says, "You gonna let your dog get away with that?!"

"Ah, he's just a bleedin' dog! Leave it out!" the Londoner replies.

"I don't like your attitude!" the policeman says.

"It wasn't my 'at he chewed, it was YOUR 'at he chewed!"
