"The Good Soldier Švejk and His Fortunes in the World War" is a satirical novel by Czech author Jaroslav Hašek, depicting the adventures of a seemingly simple-minded soldier named Josef Švejk as he navigates the absurdities of World War I within the Austro-Hungarian army, often using cunning and outlandish behavior to avoid actually fighting at the front lines; essentially, it's a classic anti-war story that uses humor to critique the insanity of war.
