As near as i can tell, the
gross mispronunciation of "
Danke Schön" may come from
Wayne Newton's
song, "Danke Schoen" where he
mispronounces it exactly as
Accipiter described.
Another quick lesson in German - the 2 dots over certain vowels is called the umlaut. You can substitute an "e" after a vowel instead of putting an umlaut over it, which may not be possible in some fonts or on some terminals.
