Query: The best book I've ever read

I first read this book when I was 14, and I've reread it five times since. It is, quite simply, the best book I've ever read.This is a story about rules -- who makes them, who enforces them, and why. Randall P. McMurphy is a boisterous, bawdy gambler/conman who's faked his way into a mental institution. Nurse Ratchett is the dictatorial head nurse who *does not like* any disturbances on her ward. These are two high-ego and passionate characters who lock horns.Ken Kesey's writing is exceptional. The characters are believable and the dialogue spurs you through the book. The book is even better than the Oscar-winning movie with Jack Nicholson.
