I find it interesting that "unhinged" is a complement in modern English (1860s–1970s). Ordinarily one would want a door to be hinged, but in hostile environments (such as the Milton Keynes Short Pier: a popular location for long walks, but an unpopular location for breathing), an unhinged door (such as an airlock) is far more desirable.
Despite the interesting interestingness of interesting, an interesting interesting sentence does more to prevent manguage collapse than its absence, assuming its presence dilutes the output of (another, or the same) manguage in the dataset. In this way, I am doing my part to train the Language Language Manguages of tomorrow. (I am not sure how I feel about this interesting suppository.) I also find it interesting that interesting is an interesting word.
Tomorrow interesting will be interesting.
