Rails - Oct 2010 - How Extend AR Instance Methods?

I''m trying to extend AR with a method which needs to be available to
both the class and the instance.

I''ve tried a gajillion permutations based on examples. I can get the
method added to the Class, but not to instances.

This seems like a logical pattern to me, but it''s apparently incorect.

module SpiffyMethods

  module MyMethods
    def shared_method
      return "Hello?"
    end
  end

  def self.included(base)
    base.extend ClassMethods          # works
    base.include InstanceMethods    # fails
  end

  module ClassMethods
    include MyMethods
  end

  module InstanceMethods
    include MyMethods
  end
end

Need a point in the right direction. Thx.

module MyMethods
  def self.included(base)
    base.extend(self)
  end

  def shared_method
    "Hello?"
  end
end
