A father decided it was about time he told his 10-year-old son about the birds and the bees so sat the lad down for a lecture. "Now" he said "I want to tell you about the Birds and the Bees"
"I don't want to know," said his son, bursting into tears. "Promise me you won't tell me."
Confused, the father asked what was wrong.
The boy sobbed, "When I was six, I got the 'There's no Easter Bunny' speech. At seven, I got the 'There's no Tooth Fairy' speech. When I was eight, you hit me with the 'There's no Santa' speech. Now, if you're going to tell me that grown-ups don't fuck, I'll have nothing left to live for."
