This thread location really sucks.

The Cleveland Indian Head Test Patterns are proud to select in the
pre-1980 category,
The Prisoner
One of my favorite TV shows, yet I have never seen the last episode.
The Prisoner is a British 1960s television drama series starring and co-created by Patrick McGoohan which combines spy fiction with elements of science fiction, allegory and psychological drama.
It follows a former British secret agent who, after abruptly resigning from his position, is held captive in a small village by the sea by an unidentified power that wishes to establish the reason for his resignation. Episodes typically feature the unnamed prisoner, labelled "Number Six" by his captors, unsuccessfully attempting to escape from or change the authority of "the Village." However, Number Six has numerous victories of his own, successfully thwarting the various individuals serving as the Village's chief administrator, "Number Two" in their attempts to break him or control the Village, causing a disconcertingly rapid turnover of personnel in the position. Eventually as the series reaches its surreal climax, Number Six's indomitable resistance and his mounting blows against the administration eventually threaten the viability of the Village itself, which forces its desperate warders to take drastic action.
