A man has six children and is very proud of his achievement. In fact, he is so proud of himself and his ability to impregnate that he starts referring to his wife as "Mother of Six" despite her constant objections.
One night, they get a chance to leave the kids behind with a sitter and go to a party. The man decides that it's time to go home and wants to find out if his wife is ready to leave as well. He shouts at the top of his voice, "Shall we go home, Mother of Six?"
His wife, irritated by her husband's lack of discretion, shouts right back, "Anytime you're ready, Father of Four."
