After having its mass glower at me from a shelf for the last six months, I finally picked up
Don Quixote. Like a lot of classics, it's something I really felt an obligation to read, and it's been a lot of fun. (The fact that Sancho was tossed in a blanket is not half as funny as the fact that he found it incredibly humiliating).
Before that, I read
Venus on the Half-Shell, that Vonnegut-inspired scifi story by "Kilgore Trout". Also fun, but the intentionally campy social-commentary probably came across better in the 70's.
