        js.executeScript("if (!window.jQuery) {" +
                "var jquery = document.createElement('script'); jquery.type = 'text/javascript';" +
                "jquery.src = 'https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js';" +
                "document.getElementsByTagName('head')[0].appendChild(jquery);" +
                "}");

        js.executeScript("$.getScript('http://the-internet.herokuapp.com/js/vendor/jquery.growl.js')");

        js.executeScript("$('head').append('<link rel=\"stylesheet\" href=\"http://the-internet.herokuapp.com/css/jquery.growl.css\" type=\"text/css\" />');");
