Besides Guys solution I'd probably would do this

class MyClass
  def get_ride_of_me(sym)
    class << self; self end.\     # overcome remove beign private ...
    __send__(:remove_method,sym.to_s)
  end

  def add_me
    def self.pingo
      p "pingo"
    end
  end
end

t  =MyClass.new
t.add_me
t.pingo   # pingo
t.get_ride_of_me(:pingo)
t.pingo     # no MethodError
