episode featuring the country called Sea Land
Sea Land DOES exist (but not to be confused with Maersk Sealand, a shipping company).
the Principality of Sea Land actually is an abandoned oil platform in the North Sea. it is now claimed by the UK, because the platform is within 12 miles of Britain (originally, the UK's territory extended only 3 miles from shore, thereby allowing Sea Land to declare itself a sovereign state).
"Real People" did a story on this 'country'. i thought it was fascinating. to the best of my knowledge, Sea Land is not recognized by any country, except maybe THe Netherlands.

generally, i didnt like the show-- i thought the good stories were few and far in between. i DO remember one week Sarah Purcell signing off at the end of the show saying "Thanks to you, we were the #1 show last week!".
