Lucifer talks about it being a bad idea that Fox canceled Bones (2005), which is a dig at Fox for canceling "Lucifer" at about the same time.
In the 1980s-themed Hell loop, Lucifer sees, and comments derisively on, the use of "guyliner" - thick eyeliner on the lower eyelid of a man. This is a callback directly to the show's first two seasons where Tom Ellis' makeup was visibly heavy with guyliner in many episodes.
Because "Lucifer" is a Warner Bros. series, the sound editors had free access to both the Looney Tunes and Hanna-Barbera libraries, utilizing a number of familiar sound effects for the animated section. The cartoons young Jimmy watches includes "Wacky Races", "Top Cat", "The Flintstones" and "Yogi Bear".
When Chloe and Lucifer first arrive in Hell, there is a slow, instrumental version of "Killing Me Softly" playing.
In the 80s part of Jimmy's hell loop, there's a cinema marquis in the background advertising Althea: Queen of Qwarks, a movie starring Chloe's mother Penelope Decker.
