I'm currently reading a Harry Potter fic that's little more than Harry and Hermione cheerfully pointing out the various idiocies of the Wizarding world. In the third chapter, there is a line that I think is one of the best I've ever read in HP fic:
"We're not messengers," Harry explained. "I'm a victim of fraud and she's the only other sane person I know."
Because, really, pre-HBP, this is so amazingly true. (Maybe it's only amusing if you have my brain.)
