Call Class Methods to Initialize Static Class

I'm trying to create a singleton class that requires some sophisticated initialization. I've boiled my problem down to this test case:

class Dumb
  attr_accessor :mything
  @my_thing = 1           # this works
  self.init_some_stuff    # this gives undefined method
  class << self
    def init_some_stuff
      @my_thing = 2
    end
    def spill_it
      puts "My Thing: #{@my_thing}"
    end
  end
end

I can initialize simple variables, but want to call class methods to do it, and I get "undefined method". Since I intend it to be used as a singleton, a constructor would not get called. What am I missing?

A method is executed whenever it is met.

  self.init_some_stuff

is placed before the definition of it. That is the problem. Place it after the definition.
