Here's one I've heard but never seen online: German engineers from the Trabant factory toured an auto assembly line in Japan. At the end of the line they witnessed a Japanese worker put a live cat inside the car and shut the doors. Puzzled, the German engineers asked their tour guide why. The guide replied, "When we come back the next morning, if the cat is dead we know the car was built airtight and thus has passed inspection." The German engineers nod and take notes. When they get back to Germany they put a cat in a Trabant and roll up the windows. When they get back the next morning the cat is gone. (The joke is that Trabants are built with engineering tolerance so poor that an animal as large as a cat could slip through the cracks.)
