That's some really great stuff! It took me some time to figure out that
you are simply extending jQuery with an existing built-in function...
Very neat.

You try to assign the Array prototype to the prototype of the jQuery
prototype, right?
After some experiments on the firebug console, I think the reason for
this no working is the Array prototype: It is just an empty error, see
for yourself:
console.debug( Array.prototype );
Therefore jQuery.fn.extend(Array.prototype) doesn't work either.
But we could just add something like this:
var arr = "reverse,pop,push,join,shift,rest of the array
methods".split(",");
for(var i=0; i<arr.length; i++) {
jQuery.fn[arr[i]] = [][arr[i]];
}
