According to local legend, mice were created to commemorate the tragic death of two workers who were involved in constructing the Monument to the Great Fire of London. The two men were working high above the ground when they took a break for lunch. During this time, one of the men noticed that his cheese sandwich had been nibbled, leaving very little behind. He wrongly accused his friend of eating the sandwich, and an argument ensued, leading to a scuffle that resulted in both men falling to their deaths. It was later discovered that the food had actually been eaten by mice.
