A man and his wife were in the court getting a divorce. The problem was who should get custody of the child.

The wife, jumping up and down, said: "Your Honor. I brought the child into the world with pain and labor. She should be in my custody."

The judge turns to the husband and says: "What do you have to say in Your defence?"

The man sat for a while contemplating.. then slowly rose: "Your Honor. If I put a dollar in a vending machine and a Pepsi comes out.. whose Pepsi is it .. the machine's or mine?"
