* ActorAllusion: At the start of ''Dirty Little Secrets'' Mike worries that Louis knows about his dirty little secret, and Harvey jokingly comments "You're Canadian?", which gets a [[SarcasmMode sarcastic laugh]] out of Mike. Patrick J. Adams, the actor who plays him, is Canadian.
** The name "Specter" for Harvey is a [[ShoutOut subtle nod]] to Gabriel Macht's role as Film/TheSpirit.
** Jacinda Barrett being cast as Zoe, one of Harvey's old flames. She and Gabriel Macht are married.
** Gina Torres says "Welcome back, Zoe", having played Zoe Washburne on {{Series/Firefly}} and {{Film/Serenity}}.
** Rachel is both half-black and a foodie, both nods to Meghan Markle.
** Both of Creator/TroianBellisario's appearances in the show revolve around Mike lying. Her most famous role is the show Series/PrettyLittleLiars. For bonus points, she plays an ex of Mike's, and engaged to Patrick J Adams, Mike's actor.
* ColbertBump: The ending song of the second episode of season 2: Time Go by Caught A Ghost.
* DuelingShows: With ''Series/MadMen''
* RealLifeRelative: Zoe is played by Gabriel Macht's real-life wife.
** Professor Gerrard is played by Gabriel Macht's real-life father.
* RealitySubtext: WordOfGod has it that Sarah Rafferty and Gabriel Macht have known each other for over 20 years. Hence the good acting chemistry between the two actors. Supposedly, he actually suggested her for the role of Donna.
* WhatCouldHaveBeen: Search for a youtube video with the words "Jessica Pearson Phillip Hardman". The idea is that instead of the whole evil embezzling Daniel Hardman, Jessica's predecessor was one Phillip Hardman (played by Victor Garber) who simply retired and is content to live in an idyllic mansion with at least his dogs while collecting dividend checks from the firm. This means that season 2 could have been a much lighter and softer season.
