For decades, two heroic statues, one male and one female, faced each other in a city park until one day, an angel came down from heaven.
"You've been such exemplary statues," the angel said, "that I'm going to give you a special gift. I'm going to bring you both to life for thirty minutes, during which time you can do anything you want." And with a clap of his hands, the angel brought the statues to life.
The two approached each other a bit shyly and dashed for the bushes, from whence there came a good deal of giggling, laughter, and shaking of branches.
Fifteen minutes later, the two statues emerged from the bushes with wide grins on their faces.
"You still have fifteen more minutes," said the angel, winking at them.
Grinning even more broadly, the female statue turned to the male statue and said, "Great! Only this time you hold the pigeon down and I'll shit on its head!"
