This one was told to me by my cousin Goga (he's on blog too)
Pedro was driving down the street in a sweat because he had an
important meeting and couldn't find a parking place. Looking up
toward heaven, he said "Lord, take pity on me. If you find me a
parking place I will go to Mass every Sunday for the rest of my
life and give up tequila."
Miraculously, a parking place appeared.
Pedro looked up again and said, "Never mind. I found one."
