A father wants to have "the" talk with his 14 year old son

'Son, the time has come for me to tell you how children are actually made!'

The boy puts his hands over his ears and yells:

'No! I don't wanna know!'

'But why not?' asks the father, surprised.

'Look, Dad! When I was 7, you told me that Santa doesn't exist. When I was 8, you told me the Easter Bunny doesn't exist either. But I'll be really pissed now if you tell me that we don't have to screw girls to make kids!'
