Have you ever bought a t-shirt with Chinese or Japanese characters in it? Have you ever wondered whether the writing in it makes sense at all? Or maybe it does make some sense, but it wouldn't really be the way Chinese or Japanese people would write something?
Well, I do not speak any Japanese or Chinese, but I think that's most likely the case. Why do I think that? I have been in Tokyo for the past week, and already spent 3 weeks here last year, and one of the things I've noticed is the funny t-shirt texts in English. Their knowledge of English language is probably close to our general knowledge of Japanese, so... you have a mess.
Things like "Behave me", or "All we need it love, is we need", or even "Laughing got tired", are very common here. I already got two of those shirts. They are awesome! :)
