As Donald Trump persecutes comedians who make fun of him, a look at WWII history shows that, under fascism, a joke can get you banned, exiled . . . or executed . . .

Hitler and Göring are standing on top of the Berlin radio tower. Hitler says he wants to do something to put a smile on the Berliners’ faces. Göring says, “Why don’t you jump?”

When a woman working in a German factory told this joke to a colleague in 1943, she was arrested by the Nazis and sentenced to death by guillotine—it didn’t matter that her husband was a good German soldier who died in battle.

In this groundbreaking work of history, Rudolph Herzog takes up such stories to show how widespread humor was during the Third Reich. It’s a fascinating and frightening history, covering the suppression of the anti-Nazi cabaret scene of the 1930s, the persecution of numerous comedians and comic film and stage actors, to the collections of “whispered jokes” that were published in the immediate aftermath of the war.

Herzog argues that jokes provide a hitherto missing chapter of WWII history. The jokes show that not all Germans were hypnotized by Nazi propaganda, and, in taking on subjects like Nazi concentration camps, they record a public acutely aware of the horrors of the regime. Thus Dead Funny is a tale of terrible silence and cowardice, but also of occasional and inspiring bravery.
