The episode prior to "The Neonatal Nomenclature" was "The Novelization Correlation." It aired on CBS on Feb. 1. It showed Amy and Sheldon discovering that Wil Wheaton's Professor Proton show is actually entertaining to watch. They also found out that Howard was a guest on the show. Howard suggested that Sheldon apologise to Wil. Thankfully, Will has forgiven Sheldon. However, when he asked Wil to be on his show, Wil asked for Amy to be his guest instead. Despite feeling jealous about it, Sheldon still encouraged Amy to be a part of Wil's show.

As for Leonard, he wrote a book based on his life. It had a protagonist named Logan Dean, who is very much like him. This character had a mean boss named Illsa. However, Bernadette pointed out that Illsa is similar to Penny, and she tells her about it. Unfortunately, this made Penny mad at Leonard. Leonard eventually called his mum for advice and figured out that Illsa is actually based on her. He decided to abandon the book because he realised he also wrote romantic tension between Illsa and Logan. Mark Cendrowski directed this episode, which was written by Eric Kaplan, Jeremy Howe and Maria Ferrari (teleplay), and Andy Gordon, Adam Faberman and Steve Holland (story).
