Whose Pepsi?

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:
"You're 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.
"You're Honour... If I put a dollar in a Pepsi Vending Machine and a
Pepsi comes out...

Whose Pepsi is it... the machines or mine?"
