I found people called McCulley Megadeth, Dragon Slayer, two people called PONCE METALLICA (YES, PONCE METALLICA) and one called LSD Metallica, at least 14 people with Anthrax in their name, including Mr Deadly Anthrax, and someone called Mr Contains Anthrax, someone called Rover Cannibal... brilliant.
When 'Lord of the Rings' came out in the cinema some cinema employee changed his name to 'Sauron the Dark Lord', he was English if i can remember correctly.
