David Rees
Maybe it's because I'm just getting out of 5 long years smack dab in the middle of corporate America, but I find David Rees' book My New Filing Technique is Unstoppable ABSOLUTELY HILARIOUS.

He captures so perfectly the utterly soul-less randomness that permeates Corporate America and seeps into the heart of it's workers. The mind numbing change of direction that comes weekly from the EXECUTIVES. The boring meetings. The inner thoughts. The sad pathetic pride that certain people take in some sad pathetic process. The arguments about things that normal people wouldn't even understand, much less care about. It's all here.

I can't recommend it highly enough. David Rees is a genius in my opinion, and I don't bestow that title easily (if anybody cares). Get Your War On is really great political satire too.

Note: For those of you likely to be offended, the language is atrocious. .. so you can pass on it.
