I read Bored of the Rings years ago and found it pretty funny, but when I tried to read it again more recently, I guess my sense of humor had changed somewhat. There’s actually a couple of other Tolkien spoofs akin to that.
I’ve only read the first one of the series, but the Discworld books are pretty amusing.
Stephen King as a dry sense of humor even amidst the horror, so I enjoy that too. But I really only like his older novels.
