The origins of the Egg Face™ are unclear. However, one common theory involves an incident in the mid to late 1980s between two north London brothers. The younger of the two was engaged in the act of defecation within the family lavatory. He had however forgotten to lock the lavatory door. His elder brother - desperate to engage in his own act of defecation - pushed the door revealing his sibling in mid defecatory push. He would later describe the face his brother made as "that of a man laying an egg".
