Subject: re-define class method

I've got the following:

module ClassMethods
   def class_method
     "Class method"
   end
end

class Thing
   extend ClassMethods
end

Thing.class_method
=> "Class method"

... and I want to change the behaviour of that method at runtime. I  
tried this:

Thing.send(:define_method, :class_method, lambda{ "replaced" })

... but I still get this:

Thing.class_method
=> "Class method"

Am I close? What's the right way to do this?

Thanks,
David
