1:52:02longboolean Q: Not extremely important, (but Krampus related), just for your information, the word "lauf" in "Krampuslauf" is pronounced more like "ou" in the words "ouch" or "couch". Even less of an issue, in German the "a" in "Krampus" is more of an "ah", more like "Krahmpus". So... "Krahmpuslouf"
