I went with the first one to truly make me laugh. That would be Pride and Prejudice. The Bennett family, especially the mother, had me laughing the whole way through. I also liked the spunky and mouthy Elizabeth Bennett. Now there's a girl that doesn't take shit from anyone!
So why is it when I write, my characters tend to be much more timid. I guess it's because I write erotica, and there needs to be a submissive. But I am working on one now where the protagonist has a bit more bite. We shall see how that turns out. I suspect the poor girl is going to be punished a lot.
So enough about me. What is your favorite romance of all time?
