Two marble statues of a man an a woman facing each other stand in an old park for centuries.
God looks at them from the above. He feels sorry for them – they're looking at each other all those centuries and yet couldn't do anything more since they're marble – so one night, when nobody's around to see, he turns them into living couple.
He says, "Okay. I made you alive and I'm letting you do whatever you've wanted to do all these years – for ten minutes. After that, I'm turning you back to marble statues"
Delighted, the now alive couple quickly dash to the nearest bushes. Moans and giggling noises can be heard. Ten minutes pass and they come out of the bushes all messy, but also smiling, relieved, and satisfied.
Looking at them all smiling, God feels sorry for them again and says, "Okay, okay, you have another ten minutes!"
As the couple run back towards the bushes, one turns towards the other and says, "This time you're holding the pigeon down and I'm shitting on it!"
