Once upon a time...

There was once a man and his dog, whom were stranded on an island. One day, the man was really desperate and wanted to have sex real bad, so he went round the island, hoping to find a woman
or something. All he found was a wooden barrel. So with that, he poked a hole through the middle of the barrel and screwed till he was satisfied. Ever since then, he used that to fulfill his sexual desires.
One day, his dog, has the sexual urge too, so it decides to use the method that its master have been using. So the two of them used the barrel until they died. About 50 years later, the island was founded by a group of old nuns and they built a nunnery there.
One day the Chief Nun found a certain barrel which contained a loadful of wax, so she took it and made them into candles. The candles were then being used to light up the nunnery in the dark until one day, a
nun got naughty and decided to satisfy herself with the candles. She thoroughly enjoyed herself from that.
However, 10 months later, she rushed into the Mother Superior's room and said, "I've got to confess, I used the
candle to screw myself 9 months ago and now I have a baby." Mother Superior then replied, "You're
more fortunate my child, I've got a puppy..."
