"The Best Little Johnny Joke"

My mate told me this, describing it as the best Little Johnny Joke. I'm inclined to agree.

Little Johnny's neighbour had a baby. Unfortunately, the baby
was born without ears.

When mother and new baby came home from the hospital, Johnny's
family was invited over to see the baby. Before they left their house,
Little Johnny's dad had a talk with him and explained that the baby had no ears.

His dad also told him that if he so much mentioned anything about
the baby's missing ears or even said the word ears, he would get the
smacking of his life when they came back home.

Little Johnny told his dad he understood completely. When
Johnny looked in the crib he said:
"What a beautiful baby." The mother
said, 'Why, Thank you Johnny."
Johnny said:
"He has beautiful little feet, beautiful little
hands, a cute little nose and really beautiful eyes. Can he see all right?"

"Yes", the mother replied, "we are so thankful; the Doctor said he
will have 20/20 Vision."

"That's great", said Little Johnny, "cos he'd be fucked if he
needed glasses!"
