Purchasing The Shoes

A shoe-seller meets a mathematician and complains that he does not know what size shoes to buy.

The shoe-seller stares at the equation for some time, then asks, "What is that symbol?" "That is the Greek letter pi." "What is pi?" "That is the ratio between the circumference and the diameter of a circle." Upon this the shoe-seller cries out: "What does a circle have to do with shoes?!"
