DOUBLE YOLKERS

Apparently the odds of getting six double yolked eggs in a carton of six is a trillion to one. Our local greengrocer used to advertise his large white hens' eggs as "double yolkers" and promised to replace any that turned out not to be. Over the years, buying a carton a week, I never had cause to ask for any to be replaced. I wonder if he or the hen realised what an extraordinary feat this was.
