You can imitate the magic jQuery behaviour as following:

//define
var _$ = {};
var $ = function(selector) {
           _$.html = function(args) {
                    alert("Doing the method 'html' with arguments " + args 
                           + " for selector " + selector);
                    return _$; //needed for pipeline
        };
        return _$; 
};

$.ajax = function(args){alert("Doing the method 'ajax' "); }

//and try
$("selector1").html("args1").html("args2");
$.ajax("args2");
