One gag manga tend to become boring very fast because it's always the same joke in the end, which may be funny for the first some times, but then you already know where it's gonna end and you don't want to read it any more. This is an exception: somehow it manages to innovate it every time just enough for you to feel that it's something new every time. It also MIGHT have an actual plot that we're yet to discover. I'm waiting, but I suppose that this will only get better.
