This isn't strictly a Sci Fi list, but they do lead off with "Bored of the Rings," a parody of Tolkein's classic Lord of the Rings.
Lots of interesting parody novels. I have read and enjoyed Cold Comfort Farm, for example, and was interested to learn that it was a parody of tbe "Loam and Lovechild" genre of novels. Who knew? I didn't even know that was the name of that type of book. I bet they could have used an infrared heater on that Cold farm. Haha
