The Good Soldier Svejk
Has anyone read "The Good Soldier Svejk" by Jaroslav Hasek? I'm reading it now and the humor is really similar to "Catch-22". I read somewhere that Joseph Heller got inspiration from it when he was writing "Catch-22."
On the back of the book, it says: "'The Good Soldier Svejk' is the classic novel of the 'little man' fighting officialdom and bureaucracy with the only weapons available to him - passive resistance, subterfuge, native wit, and dumb insolence." With the exemption of the 'dumb insolence', I'd say that's pretty much Yossarian. Although there is a huge difference between Svejk and Yossarian in that Svejk does anything he's told to do.
If you enjoyed "Catch-22", you will most likely enjoy "The Good Soldier Svejk," but, mind you, "The Good Soldier Svejk" is about twice as long and has illustrations.
