Johnny's Mother looked out the window and noticed Him "playing church" with their cat.
He had the cat sitting quietly and he was preaching to it. She smiled and went about her work.
A while later she heard loud meowing and hissing and ran back to the open window to see Johnny baptizing the cat in a tub of water.
She called out, "Johnny, stop that! The cat is afraid of water!"
Johnny looked up at her and said, "He should have thought about that before he joined my church."
