Discworld books are the epitome of dry humor and wonderful one liners. I never pass up a chance to read or re-read one. My favorite has to be "The Hog Father" though. The Oh-God of Hangovers is a must!
Now I haven't exactly written a complete Yaoi fic for FFVII yet, but I think that's because most of the characters hit me as bi-sexual anyway. Give me time and I might come up with something though.
