hello sailor!
interj.
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...).
