A father asked his ten-year-old son if he knew about the birds and the bees. "Don't tell me," pleaded the boy in some distress. "Why not?" asked his father, puzzled. "Because," explained the boy, "at seven years old I was told there was no Tooth Fairy, at eight I was told there was no Easter Bunny, at nine I was told there was no Father Christmas. So if you're now going to tell me that grown-ups don't get laid, there's nothing to live for."
