But it must be responded to by all classes.

  # true?&false?.rb
  # As suggested by Mohammad Khan

  class Object
    def true? ; false ; end
    def false? ; false ; end
  end 

  class TrueClass
    def true? ; true ; end
  end

  class FalseClass
    def false? ; true ; end
  end

Is this what you had in mind?
