A husband and wife are at Custody court and 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, and after a brief moment of silence, he says "If I put money into a Coke machine and a Coke comes out, is it mine or the machine’s ?"
