Super isn't a pointer to the parent class's implementation: it's a call
to the method you're in, but in the partent class.

  class A
    def fred(name)
       puts "hello #{name}"
    end
  end

  class B < A
    def fred(name)
       super("walter")
       super               # calls it with current params
    end
  end

  b = B.new
  b.fred("dave")

     =>  hello walter
         hello dave

         
Cheers
