Like all good laws (see Newton's for instance), there is a man behind the reality of Sod's Law, who of course, happened to go by the name of Sod; Albert Sod. Sod was born into a poor Tinker's family in London, England, 1644. Sod kept a journal of his adolescent life and onwards, detailing his many misfortunes with girls, gin, acne and the events that follow. At the age of twenty one, Sod joyfully proposed to his childhood sweetheart, Fay Warthbottom, and was preparing to go into parternship with his father in the steadily growing Tinkering business. His life seemed to be taking a turn for the better until the last of the "Great Plagues" swept through London, killing both his parents, his beloved Fay and his pet woodlouse. Distraught, Sod tried to piece his broken life back together and was buoyed by the news from a solicitor that his father had left a then considerable sum of hard earned cash under the floorboards in their small family quarters. Upon going to collect the money however, the Sod household and business was razed to the ground along with the floorboards and the cash as well as 13000 other homes as the "Great Fire" swept through England's capital. Ironically of course, the fire itself had a great impact in halting the plague that had been the cause of Albert Sod's misery - it also burnt his eyebrows, which never recovered, leaving Sod with a rather surprised (and somewhat annoyed) countenance for the rest of his days. Albert Sod never did see what was quite so "great" about either the plague or the fire.
A bitter Albert Sod spent the remainder of his days cataloging his misfortune and grievances until his dark mutterings around the streets of London became quite well known. Amoungst people who knew him, any vaguely ironic misfortune that befell them (such as it raining on a bank holiday weekend) soon became known coloquially as "the work of Sod"; and thus, Sod's Law was born.
Albert Sod died in 1688 when he bet the last of his money on a 50-1 outsider "I've got Four Knees", at the horse races. His horse miraculously came in victorious, but gave Albert Sod a nasty nip in the winner's enclosure afterwards. Albert contracted a rare equestrian disease and died alone, poor, and more than a little pissed off.
