I'm not saying it isn't funny... for the first few chapters. I got quite a kick out of it in the beginning. Eventually, however, the premise wears thin, and the concept wears itself out.
I fully recommend reading this if you want a lol, but after about five-ten chapters it didn't hold my attention anymore. There's a hint of plot scattered about (most prevalent in Lesson Zero) but it's not really followed up on.
