What the fuck are you talking about, douchebag? It's not the hardest thing in the world to translate the blackboard stuff, you know. Actually, it's easier than normal subs because it is already written down and all you gotta do is to translate it. Just because you're a moran who can't stand hardsubs, does not mean... anything I guess. Expect the fact that you're retarded, really.
The hard thing is to translate the actual content so that the original meaning doesn't get lost in translation. This is especially hard when the vast majority of the jokes are based on irony, japanese wordplay or bizarre cultural references and usually all of them at the same time.
