* 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 NataschaMcElhone.
** Hank continually refers to Marcy as "Smurf" (usually "Cokey Smurf"). Pamela Adlon 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.
* HeyItsThatGuy
** Hank's father was a high ranking inmate in Oz a while back, until Adebisi struck him with an AIDS infected needle.
*** He also made the mistake of killing [[Series/BreakingBad Gus Fring's]] partner, and wound up mute and confined to a wheelchair with nothing but a bell to communicate with.
** Judy Greer plays recurring character Trixie, Hank's favorite hooker.
** Richard Bates used to be [[Series/{{Castle}} Detective Beckett's mentor]].
** [[Series/TheOC Sandy Cohen]] is now the Dean of a girl's school.
** Jill was an [[Series/{{Numb3rs}} FBI agent]] before becoming Hank's TA.
** Looks like [[Series/VeronicaMars Vinnie Van Lowe]] hasn't changed much, going from questionable Private Eye to seedy English professor.
** StephenTobolowsky plays Stu Baggs, producer of "Fucking and Punching", who later becomes Marcy's second husband.
** Creator/CarlaGugino is Hank's attorney.
** Rob Lowe is Eddie Nero, a very... dedicated [[MethodActing method actor]].
** In another show, Daisy is probably the furthest thing from a porn star -- an [[Series/{{Bones}} intern for a forensic anthropologist]]. She didn't even change names! Still just as horny, though.
** [[Series/{{Lost}} Shannon]] is now a groupie. As a bonus, Hurley's a drug dealer!
** Marcy is played by Pamela Adlon, better known as [[WesternAnimation/KingOfTheHill Bobby Hill]] or [[WesternAnimation/{{Recess}} Spinelli]].
* HeyItsThatVoice: In the Japanese dub, [[Creator/AyaEndo Becca is]] [[MacrossFrontier Sheryl Nome]], [[QueensBlade Annelotte]] and [[Manga/LuckyStar Miyuki Takara]].
* 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.
