The Hundred-Year-Old Man Who Climbed Out the Window and Disappeared is a 2009 novel by the Swedish author Jonas Jonasson.
Here is a funny quote that I chose from the book:
Allan interrupted the two brothers by saying that he had been out and about in the world and if there was one thing he had learned it was that the very biggest and apparently most impossible conflicts on earth were based on the dialogue: “You are stupid, no, it’s you who are stupid, no it’s you who are stupid”. The solution said Allan was often to down a bottle of vodka together and then look ahead…
-“So a bottle of vodka would solve the Israel-Palestine conflict?” asked Bosse. “That stretches all the way back to the Bible”.
-“For that particular conflict you mention, it is not impossible that you would need more than one bottle”, Allan answered. “But the principle is the same”.
