Actually, the second parameter is a true or false for `include_all` private methods (see http://ruby-doc.org/core-2.0/Object.html#method-i-respond_to_missing-3F). So you can remove the `*` and simply replace it with `false` since we have no private methods on this class. I had presumed that `respond_to_missing?` took the same arguments as `respond_to?`
