  i also wonder if gsub is necessary...  there's no replacement here as 
far as i can tell.  my oversimplified monkey brain comes up with this:


irb(main):001:0> str = "John Smith - Minister of Funny Walks."
=> "John Smith - Minister of Funny Walks."
irb(main):002:0> arr = str.split(" ")
=> ["John", "Smith", "-", "Minister", "of", "Funny", "Walks."]
irb(main):003:0> name, family = arr[0], arr[1]
=> ["John", "Smith"]
irb(main):004:0> puts name
John
=> nil
irb(main):005:0> puts family
Smith
=> nil

  this also makes some assumptions about the data, of course...
