(I work in the large children’s section of a popular independent bookstore in our area.)

Customer: “Do you guys carry those train wreck books?”

Me: “Hmmm, I’m not familiar with anything like that. Is it a series, or maybe something from non-fiction?”

Customer: “Yeah, It’s a series. The Trainwreck Kids!”

(A light bulb goes on in my head.)

Me: “Oh, wait, do you mean The Boxcar Children?”

Customer: *blushes and starts to laugh* “Yeah, that’s it!”
