funny joke

There are two statues in a park; one of a nude man and one of a nude woman.
They had been facing each other across a pathway for a hundred years, when one day an angel comes down from the sky and, with a single gesture, brings the two to life.
The angel tells them, "As a reward for being so patient through a hundred blazing summers and dismal winters, you have been given life for thirty minutes to do what you've wished to do the most."
He looks at her, she looks at him, and they go running off together behind the shrubbery.
The angel waits patiently as the bushes rustle and giggling ensues. After fifteen minutes, the two return, out of breath and laughing.
The angel tells them, "Um, you have fifteen minutes left."
The male statue asks the woman statue, "Would you like to do it again?"
"Oh, yes let's," she replies! "But let's change positions. This time, I'll hold the pigeon down, and you shit on its head.
