The Goodies - Season 1

The Goodies, after being rejected from having their own legal radio station because their submission was too late, decide to start their own pirate radio station outside the five-mile limit. They then start a pirate post office using various methods of delivering mail. The power unfortunately goes to Graeme's head and he becomes a megalomaniac, trying to tow the whole of Britain outside the five-mile limit to create a "pirate state". (imdb.com)
