A lucky student was shocked to find all dozen eggs in a box were double yolks - against odds of one in a sextillion. Tom Tosetti, 17, couldn't believe his eyes when first seven eggs in the box were all doubles, and started filming - only to find the remaining five were the same. The physics and maths student at Esher College eats about a dozen eggs a week, and said it was very surprising. With 1,000 to one odds that an egg has a double yolk, the chances of 12 in a row is longer than one in a thousand trillion. The teen from Teddington, Middlesex, teen said: "Even after the second egg was cracked we knew they were something special and my mum said she had never seen two eggs like it.
