The folks at the British Egg Information Service (what the?) got tired of telling people how to properly cook an egg that they made a new self-timing egg that tells informs the "chef" when it's done.

The egg has heat-sensitive ink that displays only when the correct temperature is reached, meaning when your egg is done. The eggs come in hard-boiled, medium, or soft varieties, meaning you have to buy the kind you want or else the ink is useless—it's not a three-in-one egg.

They should really put this into other foods, like steak. Maybe they could display "WELL DONE" or "MEDIUM RARE" in big black letters when the meat reaches the right temperature. – Jason Chen
