Third Time's the Charm

Listen up, you soft little bean. The phrase 'third time's the charm' means if you fail twice, you'll succeed on the third try. Germany famously lost two really big wars (World War I and World War II). The joke is dark because it implies they are due for a third attempt at war, hoping the 'charm' kicks in. Based fact: You probably thought Germany was just a type of hot dog. Get educated!
