Dickhead
A couple had twin sons from about one year old. The first one could talk. The second one couldn't. They tryed everthing to make the little guy talk, but didn't succeed. In an act of desperation the father desided to take the child to Lourdes.
Once they got there, he immersed the child in the holy water. The kid crawled sneezing out of the water and yelled: DICKHEAD !
The father pushed the kid again in the water and again, the kid yelled: DICKHEAD, when it crawled out.
Excited the father called his wife to tell her the good news, that the child had yelled that he was a dickhead.
"that's because that's what you are" said the mother. "You took the wrong child !!!!"
