S12E06 The Computer Wore Menace Shoes
Homer gets a computer and sets up a web page as Mr. X,writing scurrilous blogs about the other townsfolk,later expanding it to make bizarre general claims. He is kidnapped and finds himself on an island to where people who know dangerous secrets are banished. It is akin to the community in television series 'The Prisoner'. Indeed he even meets Number Six,the lead character from the show and steals his boat in order to escape back to Springfield,where he beats up the German look-alike who has been impersonating him whilst he was on the island.
