“When a war starts people are forced to become soldiers. They carry guns and go to the front lines and have to kill soldiers on the other side. As many as they possibly can. Nobody cares whether you like killing other people or not. It's just something you have to do. Otherwise you're the one who gets killed." Johnnie Walker pointed his index finger at Nakata's chest. "Bang!"”
he said. "Human history in a nutshell."

“If you're going to tell people the truth, you better make them laugh; otherwise they'll kill you.”
Credited to Shaw in the lead in to the mockumentary C.S.A.: The Confederate States of America (2004) and other recent works, but this or slight variants of it are also sometimes attributed to W. C. Fields, Charlie Chaplin, and Oscar Wilde. It might possibly be derived from Shaw's statement in John Bull's Other Island (1907): "My way of joking is to tell the truth. It's the funniest joke in the world."
Another possibility is that it is derived from Shaw's characteristic of Mark Twain: "He has to put things in such a way as to make people who would otherwise hang him believe he is joking."
Variants:
If you are going to tell people the truth, you'd better make them laugh. Otherwise, they'll kill you.
