To access a class method from an instance, you have to use a reference to that class (because that’s where the method resides). The attribute reader returning that reference is named class :

class Monkey
  def Monkey.laughs
     "Ou ou ou Ahh ahh AHHH!" #that's how a monkey laughs
  end
end
mvp = Monkey.new
mvp.class.laughs
