* You may notice Doug Walker (in the style of Doug Funnie--the Nostalgia Critic was not amused) making a cameo on the Familiar Faces poster.
* The Spirit that tries to torment CR is most definitely not Creator/TommyWiseau.
* He's done three different Shout Outs to ''VideoGame/TeamFortress2'': First interjecting "Gentlemen." and the "Meet the..." title sting into the ''ComicStrip/SpyVsSpy'' episode, then using a quote from "Meet the Medic" in his ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' review, and finally, overdubbing the Administrator's quotes into the Samhain episode.
* He has The Comedian's bloody smiley-face pin from ''ComicBook/{{Watchmen}}'' on his jacket.
* When his face was finally revealed by ''WebVideo/TheNostalgiaCritic'', CR hides behind the newspaper he had been reading and quotes ''Film/TheWizardOfOz'' by saying "This is CR. Pay no attention to the man behind the newspaper."
* A subtle one, but in his review of "Swarm of the Century", after Applejack says "Didn't see that comin'", Chad [[WesternAnimation/JohnnyTest adds a red highlight to her mane]].
