O hai there children. You know, you can learn a lot of things from Plato. And Shakespeare. And other geezers with huge foreheads. Lulz (a corruption of "lol" or "laugh out loud") is not merely a collection of faxx, concepts, and useful knowledge about AIDS and MS Paint, or even the systematic investigation of the moustache phenomenon, although all are common definitions of lulz.
Let the education begin.
To start off, you should probably be acquainted with the lulz centres of the internets, obtain basic MS Paint skillz, and learn how to operate heavy machinery under the influence. Feel free to introduce yourself, and post macros of Dali's 'tache, of course.
