A man and his wife were in a court for their divorce case. The problem was who should get custody of the child. The wife screamed and jumped up and said: "Your Honour, I brought the child into the world with all the pain and labour. The child should be in my custody." The judge turned to the husband and said: "What do you have to say in your defence?" The man sat for a while contemplating then slowly rose. "Your Honour, If I put a dollar in a Pepsi Vending Machine and a Pepsi comes out... whose Pepsi is it... the machine's or mine?"
