Good morning. I'm Noel King. July 3 was a busy day for a maternity ward in Ohio. The Mansfield News Journal reports that three sisters - Daneesha Haynes, Ashley Haynes and Ariel Williams - all gave birth on the same day within 4 1/2 hours of each other and with the help of the same doctor. The odds of this happening are about 1 in 50 million. Their grandmother joked that in the future, they won't need to invite other kids to their birthday parties.
