Alex Wagner, a wealthy 82 year old businessman, marries Elie, a 24 year old girl from the country.
A year goes by and Elie delivers a baby. Dr. Johnson comes out of the delivery room and congratulates Alex telling him that his wife gave birth to a healthy baby boy.
The old man says proudly, "The old machine is still up and running!"
A year later, Elie gives birth to another child. Dr. Johnson comes out of the delivery room and congratulates the old man telling him that his wife gave birth to a healthy baby girl. Old Alex says proudly, "The old machine is still up and running!"
Another year goes by and Elie delivers a third baby. Dr. Johnson again greets and congratulates the old businessman for a son that his wife had delivered again. Alex is elated and announces once again, "The old
machine is still up and running!"
The good doctor can't take it any more, so he blurts out, "I know, but I suggest you get the oil changed because this one is black!"
