Dad asks his son, now aged 10, if he knows about the birds and the bees.

"I don't want to know!" the child said, bursting into tears.

Confused, the father asked his son what was wrong.

"Oh Dad," he sobbed, "at age six I got the 'there's no Santa' speech. At age seven I got the 'there's no Easter bunny' speech. Then at age 8 you hit me with the 'there's no tooth fairy' speech! If you're going to tell me now that grown-ups don't really screw, I've got nothing left to live for!"
