In this episode of Wow, I Never Knew That, if you ever go camping there is one thing you do not want to leave home without, the SWISS ARMY KNIFE. We'll explain how it evolved into the most famous knife in the world and how the company's name got "CUT" together. And there is nothing like 18 rounds of golf on a beautiful large golf course. But what if you had a space issue, but still wanted to play, learn the origin behind its smaller alternative, MINIATURE GOLF. And where did the term CUP OF JOE come from as well as the word JAVA. And it's an explosive idea, but how did the inventor of the PEACE PRIZE invent DYNAMITE. And we all love a juicy HAMBURGER, so where did these chopped meat patties come from? And why do we say KNOCK ON WOOD to make sure nothing bad happens?
