Dilbert. Office Space. The Office. And now ... Company.
Every so often, something comes along that just nails corporate life so perfectly. I recently finished reading Company by Max Barry.
Company is a ruthless and hysterical sendup of all things that make corporate life ever so much fun. The ending kind of starts to run out of steam but the humor will last long after you forget how it ends. At the very least, check it out from the library. Or better yet, do what I did and borrow it from a co-worker.
