Guardian Angel

Sorry if this joke is already posted up:)

A man is walking down the street and he hears in his head. "Stop! If u take one more step u will die!" The man stops and a brick lands at his feet. He keeps walking not watching where he was going and the voice says again. "Stop! If u take one more step u will regret it for the rest of ur life!" The man stops and a lorry comes roaring by almost hitting him. He thinks to himself "Who is telling me this?" The voice answers "U won't believe this but, I am ur guardian angel and I am here to protect u." The man thinks to himself "Where the hell were u on my wedding day?"
