Sona recommended 50 Shades Of Grey to Conan.

The episode features a playful exchange between Conan O'Brien and Sona Movsesian, where Sona playfully criticizes Conan's reading habits. She points out that while Conan dedicates a significant amount of time to reading history books, he tends to disregard her personal book recommendations.

This led to Sona specifically mentioning "Fifty Shades of Grey" as an example of a book Conan hasn't read, despite her recommendations. The conversation quickly took a humorous turn as the group discussed the idea of Conan making a documentary about "Fifty Shades of Grey."

The humor escalated with a comedic comparison of "Fifty Shades of Grey" to historical documentaries, particularly "The Blue and the Gray," a series about the Civil War. The suggestion was made to reimagine the Civil War with explicit elements, culminating in the line, "Imagine the Civil War with spanking," highlighting the absurdity and comedic contrast between Conan's usual intellectual pursuits and Sona's suggested reading.
