Jim was working on a building site when a roof collapsed. He was struck on the head by falling tiles, one of which sliced his left ear clean off. His friends took Jim and his ear to the hospital, but it was no go. The ear was too badly damaged to be sewn back on.
"There is an alternative" says the young doctor in charge. "At this hospital we have been experimenting with sewing a pig's ear on as a replacement. Could we try that with you?".
Jim readily agreed and the procedure went ahead without a hitch. Six weeks later he was back in for tests to see if the operation had been successful.
"We're going to put a pair of headphones on you" says the doctor. "We will play sounds through the right ear first, then the left, your new ear. If you here a sound, tap the table top. Ready?" And off they went.
Sounds through the right ear. Tap, tap.
Sounds through the left ear. Nothing.
Try again.
Sounds through the right ear. Tap, tap.
Sounds through the left ear. Nothing.
"Is there a problem?" Says the doc. "You seem to have problems hearing with the new ear?"
"I'm sorry doc" says Jim, "but there's a lot of crackling...."

They made a pig's ear of that then?

There's no ham in it though...
