Germans do have humor. It is actually not that different from English humor in style.
The idea that Germans have no humor comes from a number of reasons. To understand a foreign joke, you need a thorough grasp of that language. And this applies to any foreign language - I could not understand e.g. a French joke, but I would not deny that they most likely love humor, too.
Then, most English or American peoples impression of Germans stem from times of war or shortly after - only a small minority bothered to update their views later. During the war, allied propaganda had obviously different goals than promote German humor or Germans as funny people. And people in the early years of post-war Germany had not much to laugh about in life, their prime job was to survive in less than funny circumstances.
