Easiest implementation of "some_method" in Ruby?

     a = %w|a b|
     b = %w|a x|
     c = %w|x y|

  some_method(a,b,c)

  #=>

   [ ["a", "a", "x"]
     ["a", "a", "y"]
     ["a", "x", "x"]
     ["a", "x", "y"]
     ["b", "a", "x"]
     ["b", "a", "y"]
     ["b", "x", "x"]
     ["b", "x", "y"] ]
  
Order doesn't really matter.
