I used to believe that when a farmer got eggs form one of his prize chickens he'd mark the egg with a black cross. Of course it was my mum doing it. Fast forward twenty years and i'm in the supermarket and girlfriend picks up some eggs "oh hold on" i say "let me check them to see if there are any special eggs". Much hilarity ensued and still does - at my expense.
