Two statues, one male and one female, had, for years stood facing each other
across a park square. One day, an angel appears in the square and addresses
the two statues. 

"You two have stood here for years, and provided such inspiration to passers
by, that I have come to grant you a favor. For the next 30 minutes, you will
be brought to life and be fully human. You may use this time in any way you
wish to fulfill your fondest wishes."

With a flash of light, and a faint tinkling of bells, the angel disappears, 
and the two statues come to life. They approach each other, and begin talking.
Within moments, the two have disappeared from sight, but can be heard giggling
behind the bushes. After about 15 minutes, they emerge from the bushes, 
looking somewhat disheveled and picking leaves from their hair, but smiling
broadly.

The male turns to the female and says, "We still have another fifteen minutes.
Do you want to do it again?"

The female smiles and replies, "Sure, but this time, you hold the pigeon,
and I'll crap on its head."
