This bloke loses both of his ears in an accident. The surgeon tells him that there are no human transplant ears available but they have a dog's ear and a pig's ear ready to transplant, so he agrees to the operation.
One month later, he goes back for a check up and the doc asks him how he is getting on with his new ears.
"Well, doctor,", the bloke says, "the dog ear is brilliant - I can hear for miles and no bastard ever talks behind my back - but with the pigs ear....I seem to be getting a lot of crackling in it."
