Those 5 lines are easy to refactor like this:

```js
(function() {
  var uz = document.createElement('script');
  uz.src = '//cdn4.userzoom.com/trueintent/js/uz_til.js?cuid=D32DB4D34334418399C4C7B3626B05B1';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(uz, s);
})();
```

Just my 2p.
