JQuery is often very useful for taking some page statistics and other things , just make a $('.elemento').each(callback) and you can start to know what is happening on the page.
The problem is that this relies on the page doing the load of jQuery; if not, there is no way, it has to be pure JS.
Is there any way to force the loading of jQ on any page, eg Google?

Just do paste of the code in the console and jQuery will be loaded. We can then use it freely on the console. Slightly adapted:
var jq = document.createElement('script');
jq.src = "//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);
// ... dar um tempinho pro script carregar
setTimeout( function(){
jQuery.noConflict();
$=jQuery;
console.log('Carregado jQuery v' + $.fn.jquery);
}, 3000);
To make it easier to use the snippet we can save it as a ... snippet !, within Chrome Developer Tools itself:
