It's a man and a woman who do not know how to make babies, so they call the doctor:
- Hello Doctor, how do you have to have a baby?
- We must put the sensitive point of the woman on that of the man.
- Very good, thank you Doctor, goodbye.
The couple decided to apply his advice goes up in the room.
- Honey, what's your sore point?
- "well it is my ears," said the man. "And you ?"
- "for me, it's my buttocks". Said the woman.
So, they start to put themselves in position to make a baby, the woman's buttocks on the man's ear, and there the woman drops a big, foolish fart, and the man then says:
- And honey, it's starting to come, I hear the baby arrive by moped!
