 "Guy Love" was composed by Fordham and Perry. It was a late addition to the episode, brought on because, according to Bill Lawrence, "All the modern musicals like Jekyll & Hyde have these really overwrought love songs, so we really wanted to have one between J.D. and Turk." It was the hardest song for Fordham to write. She met with Perry for help with the lyrics, and he gave her the hook, "It's guy love, between two guys." The writing became easier, but she still wanted a reference to a tender moment between Turk and J.D. She emailed D'Abruzzo, who she knew to be a big fan of the show, "and, no exaggeration, five minutes later, she sent me a list of 30 [moments]", including Turk performing an appendectomy on J.D. in "My Day Off". At first, the song was meant to be a power ballad.
