Hey do you think a reference to something is a joke, have you ever watched lucky star and laughed because wow i know that thing! thats an anime i watched! then leave because you aren't funny and you've never been funny nobody has ever said you were funny and nobody ever will. If you're content with that life then fine but this anime isnt for you. This anime is about people who understand the structure of a joke, it's a set up then a punchline. And it does that greatly. But if you just think the reference is a joke then go back to watchinglucky star.
