While "lentokonesuihkuturbinimoottoriapumekaanikkoaliupseerioppilas" is a correct, and possibly used word, I didn't find it commonly used enough to be included. "Kumarreksituteskenteleentuvaisehkollaismaisekkuudellisenneskenteluttelemattomammuuksissansakkaankopahan" and "epäjärjestelmällistyttämättömyydelläänsäkäänköhänkään" are also long compound words, but I cannot verify if they are correct and they're in any case too long to be actually used.
The examples removed were bad, 13-year-old, "hee-hee, you said 'rise'!" style jokes, not fitting into an accurate, quality article like this.
The changed "Correct Answers" was incorrect and stupid.
