Occasional West Coast equivalent of hello world; seems to have originated at SAIL, later associated with the game Zork (which also included “hello, aviator” and “hello, implementor”). Originally from the traditional hooker's greeting to a swabbie fresh off the boat, of course. The standard response is “Nothing happens here.”; of all the Zork/Dungeon games, only in Infocom's Zork 3 is “Hello, Sailor” actually useful (excluding the unique situation where _knowing_ this fact is important in Dungeon...).
