I'm in the car on the way to lunch, where I'm discussing the Dresden Files and DFRPG with my wife. In all fairness, she's a huge Dresden fan too, but the comment was priceless:
Her: "What happened in that book again?"
Me: "It's the one where [X plot] happens."
Her: "Oh, right, with the Delorean guys?"
Me: "..."
Yes, she meant Denarian. She said Delorean. I laughed all the way home, she punched me a couple times. It was worth it.
