The 24 year old kid, his girlfriend, and his wife

So there was this 24 year old kid. And he went and got his girlfriend pregnant. The girlfriends's mother, of course, was very upset. The mother insisted that the kid should marry her daughter. Unfortunately the kid was already married. So the pregnant girl's mother called the kid's wife, telling her to divorce the 24 year old kid so that he could marry her daughter. The wife said no way. But the girl's mother was persistant. She kept calling and calling, pleading with the kid's wife, sometimes screaming at her, begging her to divorce the 24 year old kid. But the wife would yell back. "Leave me alone. He's my husband." Finally, the pregnant girl's mother decided to confront the wife in person. So one day, when the 24 year old kid was at work, she drove over to their house and pounded on the door. A little boy 4 years old opened the door. Then a little girl 3 years old also came to the door. Finally, the kid's wife, carring a 1 year old, and also 6 months pregnant, came to the door. The mother looked at the children, then looked at the wife and said "You can keep him."
