Scrotal Fission
A theory in evolution explaining why the male human specimen developed two voluptuous balls instead of keeping the standard one nard. The evolutionary process began shortly after 1901 when Hubert Cecil Booth invented the vacuum cleaner. It is perceived in old written scripture that angry housewives would often explode on their male counter parts and suck their poor sad little dangler right up the vacuum hose. Thus forcing men to develop a second nut.
The first signs of SCROTAL FISSION were noticed in 1909, when Dr. Edbert Cockle was fondling a young man behind a desk, when had noticed a strange bulge in the boys scrotum next to his nut.
