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.
