Years ago there was a baker’s assistant whose sole job was to pour the dough mixture for making sausage rolls (apparently the royal family loved sausage). Because people were identified by their professions, he was just called Richard the Pourer.
One day Richard ran out of some key ingredients, namely a secret spice he used in the batter. He called his apprentice and sent him to the store to buy more spices. When the apprentice arrived at the store, he found that he had forgotten the name of the ingredient.
