I was making eggs for lunch and cracked one and it exploded. Yucky green rotten egg, stunk up my kitchen and made a big mess. The eggs were a couple of weeks past the best buy date but still. They have been refridgerated. Now I'm really put off buying any more store bought eggs. I tested the rest by putting them in water and the rest in the carton all sunk to the bottom so they should be okay but I think I'll feed them to the dog.
