“Who needs a phone when you can yodel?”
Every morning, the Pretzel Girl dresses up in her traditional clothes and climbs up to the hills to practice her yodeling. She has to do it far away from her village, because her very impressive yodel can be heard for miles around and has been known to occasionally cause avalanches.
With the sheer volume and pitch-changes of her yodeling song, the Pretzel Girl shares all of the latest news with her fellow yodelers in distant towns, and they yodel right back with everything that’s going on with them. It might be easier to use a phone or e-mail, but somehow it just wouldn’t be as much fun!
