Logic

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 Honor. I brought the
child into the world with all the pain and labor. The child  should be in
my custody."

The judge turned to the husband and said: "What do you have to say in
your defense?"

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