How the crap do I use define_method in a module? -- needs "self.included"

sample.rb

module SampleMod

  def self.included(base)
    [:one, :two, :three].each do |method_name|
      define_method method_name do
        puts "inside #{method_name}"
      end
    end
  end

end

class A
  include SampleMod

  define_method :sample do
    puts "inside sample"
  end
end

A.new.send(:sample)
begin
  A.new.send(:one)
rescue
  puts "Crap it didn't work"
end
