A man had six children and was very proud of his achievement. He was so proud of himself that for years he called his wife "Mother of Six," in spite of her objections.
One night in their retirement years they go to a party. The man is ready 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 for so many years, shouts back, "Anytime you're ready, Father of Four!"
