Rudolph Herzog said this quote
“ The historical record contradicts the assumption that the Nazis sentenced large numbers of people to death during World War II for telling jokes. In the final phase of the Third Reich, some cases did receive capital sentences, but they were extreme exceptions to the rule. (We will return to them later.) The compilations of jokes that circulated in Germany after the war bore titles like Deadly Laughter and When Laughter Was Dangerous, but there is not much evidence that the jokes they contained were inevitably risky for the teller. ”
