A father asked his son, Little Johnny, now aged 10, if he knew about the birds and the bees yet.
"I don't want to know!" little Johnny said, bursting into tears.
Confused, the father asked Little Johnny what was wrong.
"Oh Dad," Johnny sobbed, "At age 6 I got the 'there's no Santa' speech. At age 7 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!"
