A man had six children and was very proud of his achievement. He was so proud of himself that he started calling his wife 'Mother of Six' in spite of her objections.

One night they attended a party. When the man decided it was time to go home, and wanted to find out if his wife was ready to leave as well, he shouted across the room at the top of his voice, 'Shall we go home Mother of Six?'

His wife, irritated by her husbands lack of discretion, finally shouted back: 'Anytime you're ready, Father of Four!'
