Years ago, I delivered twins. They were a boy and a girl. The day they were born, the head nurse brought them out for their father to see. He could hardly believe his good fortune. The baby girl had a pink blanket wrapped around her, and the baby boy was enclosed in a blue blanket. He took one step forward just so he could touch the babies and believe they had finally arrived.

As he started to touch them, the nurse took a step backward and said, "You can't touch those babies. You aren't sterile!"

Without missing a beat and with a big smile, the husband boasted, "You betcha I'm not!"
