Who are you & where are you?

Walking down the street, a man hears a voice: Stop! If you take one more step, a brick will fall down and kill you. The man stopped; a big brick fell in front of him. The astonished man continued walking to the cross walk. The voice shouted, Stop! If you take one more step, a car will run over you and you will die. The man stood still; a car came careening around the corner, barely missing him. Where are you? the man asked. Who are you? I am your guardian angel, the voice answered. Oh yeah? the man asked. Where the hell were you when I got married last week?
