While editing together the episode, Sean McGann realized he had forgotten to record his final thoughts on the episode (where he describes his thoughts on both parts of the series premiere through voice-over). With only one minute left on his camcorder and his tripod not in its original position, McGann deleted a few of his takes on the camera and recorded his remaining dialogue while seated at his desk, with the camera filming the corner of his bed.
Approximately three times, a video titled "The Extended Weekend of Sparkle" is mentioned and/or shown. "The Extended Weekend of Sparkle" is a 17-minute YouTube Poop by YouTube user Combuskenisawesome that uses episodes of My Little Pony: Friendship Is Magic (2010) as its main source. Sean McGann had watched this video during the time he was writing his review of "Elements of Harmony" and has since written a review on the forum YouChew, reviewing "The Extended Weekend of Sparkle" and saying that it was his new favorite YouTube Poop of all time and is proof that YTPs can be art.
