Based on chris coyiers konami code, adds konami class to html to override styles and triggers jquery event "KONAMI_CODE" for js fun.

lol.konami.js

var kkeys = [], konami = "38,38,40,40,37,39,37,39,66,65";

$(document).keydown(function(e) {

  kkeys.push( e.keyCode );

  if ( kkeys.toString().indexOf( konami ) >= 0 ) {

    $(document).unbind('keydown',arguments.callee);

    // do something awesome
    $("html").addClass("konami");
    $(window).trigger('KONAMI_CODE');

  }

});
