Belated Guardian Angel

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?
