attachEvent polyfill I made for my buddy @leandrooriente, who is nuts about IE. Now you can enjoy your Micro$oft event handlers everywhere! I'm a douchebag.

attachEvent-polyfill.js
(function(win){
if(win.attachEvent) return;
var attachEvent = function(on, callback) {
var on = on.substring(2,on.length);
return this.addEventListener(on, callback);
}
win.Element.prototype.attachEvent = attachEvent;
})(window);
