Adolf Hitler Told Bad Jokes To Nazi Friends

Adolf Hitler took time out from running Nazi Germany to tell jokes to his fellow henchmen and generals a new book claims. The dictator would often break from the serious nature of waging his campaign to tell 'knock knock' and 'mother in law' jokes. According to the book by the last surviving member of his bunker, "Hitler often practiced his jokes on us to keep our spirits up. One of his favourites was the joke about the Polish man who walks into bar but i can't remember the ending".
