One for the weekend

An angel swoops down to tow Statues facing eachother, a male and female. For being so good for so long, the angel grants them 30 minutes of freedom and brings them to life. The male looks gleefully at the female, takes her hand and they escape into the bushes. 15 minutes later they re-appear with twigs sticking out from all kinds of places, slightly red-faced and very happy. The angel tells them they still have 15 minutes to go. The female looks longlingly to the male statue and says; "This time you hold the pigeon down and i'll crap on his head".
