Colbert Bump: In his re-upload of "Alliances", mentions and quotes part of the review given by The Agony Booth for that episode, joking that people are clearly trying to hassle in on his niche.
Also drops one towards fellow reviewer Confused Matthew, who occasionally he's collaborated with.
Received multiple from Linkara, who freely admits to being a fanboy of his.
In fact Confused Matthew and Linkara's sites are directly linked to from the footer on his website. The only websites other than his own that he links to that way.
Creator Backlash: While Chuck isn't out-and-out ashamed that he ever got involved with Channel Awesome, unlike many of its other former contributors, he did say after his departure in 2018 that he had in retrospect gained very little from being part of the site.
Averted that Chuck won't be doing the Star Wars prequels, following in the vein of Confused Matthew or RedLetterMedia, simply because of the redundancy. "Its been done, there's nothing left to be said".
Keep Circulating the Tapes: Some fans tried to do this after Chuck removed all of his early reviews from YouTube, by re-uploading copies of his video reviews to the site. Unfortunately, all they ended up doing was proving that Chuck's decision had been the right one, as Viacom squashed the new uploads almost as soon as they went up. Some fan-made archives still exist, off of YouTube, though they aren't too easy to find. The original videos are not 100% identical to the remade ones, so they still remain archive-worthy.

Reclusive Artist: Sort of. While he is active on Twitter and interacts with people, nobody knows what the hell he looks like even after over a full decade of reviews.
Schedule Slip: The only time when he doesn't post new reviews is when he has to change video hosting services, which admittedly is not a rare occurrence at this point.
Screwed by the Lawyers: He notes that his legal experience is basically limited to "not singing Ninety-nine [sic] Luftballons", (which was the dropped intro music of TNG on YouTube).
Misc. Trivia:
One of his most famous catch phrases, "I'm just a viewer with an opinion," was intended only for the first episode... but it kept going because he found it so appropriate.
