How many Women can a Man marry?

Little Johnny was attending his first Wedding. After the Service, his cousin asked him, “How many Women can a Man marry?”
“Sixteen!” the Little Johnny responded.

His Cousin was amazed that he had an answer so quickly, “How do you know that?” She asked.
“Easy!” Little Johnny said, “all you have to do is add it up like the Bishop said. 4 better, 4 Worse, 4 Richer, 4 Poor..!”
