There were two statues in the park. A naked man and a naked woman. They had been there for 100 years.
An angel came and visited them and said: "Because of your long and faithful service you are each granted 30 minutes of life to do whatever you please."
The man looked at the woman, they giggled and ran into the bushes. For about 15 minutes there was a lot of rustling and giggling and oooohhhs and aaahhhs. Then both came out.
The angel looked at his watch and said: "Well you still have 15 minutes left. Would you like to do that again?"
The woman looked at the man and said: "Let's do it. Only this time I want to change positions. This time you hold the pigeon down and I'll poop on its head."
