you're doing some food shopping in the supermarket when you remember that you're out of eggs so you wander over to the egg section and buy a 6pack of 'large' free range eggs. Once home you put the foodage where it belongs; tins and whatnot in the cupboard and eggs in the fridge.

Just then the phone rings. It's the manager of the local branch of Tesco Express and it transpires that one of the eggs in the carton now residing in your refrigerator is a racist.
