We don't play guitars (but we love them)

The emergency blanket, contrary to what you may have been told, was invented in 1654 by Hanz Eier Von Huhn. He was the first man to conceive, design and build an emergency blanket for the use it has today. His first attempt had some design problems, it turned out to be too big, it could only be used by giants or 100 people together plus it weighted 100 pounds. He tried to solve this problem without any luck for many years until he went crazy in 1655. While crazy and committed to an institution Hanz devoted his attention on making the perfect stew.
