You left it pretty wide open as far as what kinds of books you were looking for.
funny crude humor : anything by christoper moore. If you're easily offended steer clear from but if you enjoy drug culture / crude / satrical humor Christopher Moore is the funniest author crancking out books right now. Practical Demonkeeping is the newest and as far as I'm concerned the funniest, but Lamb and Fluke are a close second and third.
If you like stream of conscience type of reading (the author basically tells a story as if he was thinking it in his head) Kurt Vonnagut is fantastic. Anything you pick up by him is good.
Dan Brown (Davinci Code) is a really good Nonfiction author. He uses historical facts and kinda fills in the blanks with possibilities to write some excellent dramas. Davinci Code is his most popular but I like Angels and Demons better. Stay away from Digital Fortress unless you read it first, because his other books are leaps and bounds better.
The book Hot Climates for Fierce Invalids is good if you decide vonnagut is a bit too musty but still like stream of conscience style of writing. I forget the authors name but he tells really good stories, makes you pay attention because the plot is handed to you in pieces, and has a much more tangable sense of humor than vonnagut. Vonnagut humor is very dry and sometimes hard to get, this guy kinda smacks you in the face with it by comparison.
there's also a book called Underboss if youre interested in mafia or organized crime. Again, I forget the authors name but the book is a historical look at the Gambino crime family circa valentines day massacre and up to John Gotti taking over. The book is kinda the life story of Gotti's eventual underboss who ended up being the guy that turned states evidence to get gotti put away for life.
if you want books to help your business savvy Richard Templar writes The Rules of Management and The Rules of Work. I habitually buy copies of the rules of work for all of my employees I wish to keep long term. And the rules of management really helped me become a better leader.
as far as autobiographies or books by fameous people George Carlin, Jimmy Buffet, Richard Prior, and believe it or not Michael Jordan were really interesting. Carlin and Prior are haliarous. again steer clean though if you're easily offended. Also see anything by or about kevin smith.
There's really a million suggestions I can offer but I don't wanna bog you down. Some of my best discoveries have come from flea market 50 cent boxes and used book stores just by asking whoever worked there.
Except for the business books and the books by celebs all my recomendations are extremely difficult reads. Your average high school reader would struggle greatly with most of the fore mentioned books. Heck, sometimes I even have to reread something vonnagut wrote to fully understand what he's talking about. And too, most of these books have lots of cussing and sexual references.
