Famed composer Johann Strauss was an avid mountain climber who once waltzed himself into deep trouble. He lost his footing and found himself hanging by his fingertips over a bottomless gorge.

Another climber heroically came to his rescue and just managed to grab Johann by a strap of his backpack to save the Maestro's life.

Since then, the act of trying to get out of a seemingly hopeless situation has come to be known as grasping at Strauss.
