WHERE IS THE HAT?

Once there was a man who lost his hat and thought he can have another one by stealing a hat from the church entrance. Once inside, he heard the sermon of the priest about the ten commandments. When the mass was over he approach the priest. "Father I would like to thank you. I went here with a sin in my heart but when I heard your sermon I have changed my mind". "Fine" said the priest. "But what did I say that change your mind?". "Remember Father when you said -Thou shall not covet thy neighbor's wife- then I remember where I left my heart.
