* ActorAllusion:
** During season three, Ken Marino from ''TheState'' made an appearance. He's best known for his character [[http://www.youtube.com/watch?v=gR1hI_Ikuv8 Louie]], The Guy Who Says His CatchPhrase Over and Over Again. After successfully cock-blocking him, Hank tells him to make a cup of tea and "dip his balls in it".
** When Hank's lawyer makes him wear a suit for his court hearing, he notes that he "[[Series/TheXFiles looks like an FBI agent.]]" A double ShoutOut when Karen responds he looks like a "[[http://www.youtube.com/watch?v=Wijp4-3giNw brooding and comely]] FBI agent."
** Charlie Runkle and Evan Handler are Jewish.
** In the Season 6 opener, Hank tells Karen that she looks "like a Sascha or a Pascha, definitely an -ascha." Karen is played by actress Creator/NataschaMcElhone.
** Hank continually refers to Marcy as "Smurf" (usually "Cokey Smurf"). Creator/PamelaAdlon played Kelly on ''Series/TheFactsOfLife''; during the episode "Small But Dangerous," Jo refers to Kelly as "Smurf."
* DawsonCasting:
** Mia, whose age of 16 is an important plot point, is played by an actress who is in her early 20s, and visibly so. The fact that she looks much older is also an important plot point. It also doesn't help that MadelineZima is [[TeensAreShort 5'8"]].
** Averted with Madeleine Martin (Becca), notable given this show is NOT kid friendly.
* {{Defictionalization}}: You can read Hank's book ''[[https://www.goodreads.com/book/show/5460398-god-hates-us-all God Hates Us All]]'' for yourself. The plot of the book hardly has anything to do with that of the series, though.
* GeniusBonus: The show is filled with classic rock and heavy metal references. In fact, Hank's books ''South of Heaven'', ''Seasons in the Abyss'', and ''God Hates Us All'' are named after albums from American thrash metal band Music/{{Slayer}}.
* RetroactiveRecognition: Becca's boyfriend Tyler is also [[Disney/{{Frozen}} Kristoff]] in ''Series/OnceUponATime''.
* JustForFun/NamesTheSame: This was grounds for a lawsuit by the band Music/RedHotChiliPeppers, as the show shares its name with an album and a song by the band. The case did not reach a courtroom.
