I love the word tschüß so much. It's got every German squerk in it: four consonants piled at the front, an umlaut over the U, and the esszet at the end. No "normal" linguistic real estate--no part of it confusingly like the English, no part of it negotiable. All weird, all the time (like if there were the word çâéÿè in French or something). I used to love writing tschüß in German class--apparently still do!
