Custody Court

A Husband and Wife at Custody court. The judge looks sternly at the ex wife.
Judge: “Why do you think you deserve custody of the child?”
Ex wife: “I brought him into this world so I should have custody of him.”
Judge: “That is a simple yet good reason.”
Then the judge looks towards the Ex husband.
Judge: “Why do you think you deserve custody of the child, sir?”
The ex husband thought long and hard about his response, after a brief moment of silence, he replies, “If I put money into a Pepsi machine and a Pepsi comes out. Is it mine or the machines?”
