Little Johnny was sitting on the fence, watching a bull with two cows when the preacher walked up and asked Johnny what he was doing.

Johnny replied, "I’m watching that bull screw that black cow." The preacher was shocked.

"John, you shouldn’t use that word. Instead, say the bull is going to ‘surprise’ the black cow."

"Okay," said Johnny.

The preacher continued on his walk. The next Sunday, the preacher was shaking hands with his parishioners as they left church when Little Johnny appeared with his parents.

The preacher bent down, smiled, and asked, "So, Johnnie, did that bull ‘surprise’ the black cow?"

Johnny replied, "He sure did! He screwed the white one!"
