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," he announced to them, "that I'm going to give you a special gift. I'm going to bring you both to life for thirty minutes, in which 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, but soon dashed for the bushes, from which shortly emerged a good deal of giggling, laughter, and shaking of branches. Fifteen minutes later, the two statues emerged from the bushes, wide grins on their faces.

"You still have fifteen more minutes," said the angel, winking at them.

Grinning even more widely the female statue turned to the male statue and said, "Great! Only this time you hold the pigeon down and I'll crap on its head."
