I was playing a game the other day where we had to quote things, and got told I could quote fan fiction, and started quoting Transfigurations, specifically "Malfoy wasn't really dirty, but Harry found a smear between navel and hipbone and licked it with showy thoroughness" (I think I got it right).

Three people promptly asked me for the URL, saying "I've GOT to read this!"

I was amused.
