Alternative Character Interpretation: Some have suggested that Karasuma volunteering Alice was actually an attempt to punish/get back at her for correcting her in the middle of class.
Big-Lipped Alligator Moment: This is a light-hearted comedy series, so it's not like anything is meant to be taken too seriously... but the musical number Shino narrates from the middle of episode 12 onward pretty much comes out of left field. How does one go from talking about chuunibyou to the Little Mermaid anyway?
As of season two Honoka Matsubara has become popular as a character who loves Karen almost as much as the fandom, as well as moving Karen out of the Third Wheel House. She also made the cut on the launch day roster of Kirara Fantasia for this reason, which is no small feat for a Massive Multiplayer Crossover.
Kuzehashi-sensei and her attempts to become more open with her "Cute" students have endeared her to many fans.
"Get Married! Get Married!"note In the beginning of the opening theme song,the word kekkou(結構, 'fine, very well' or 'quite, pretty much') can be easily misheard as kekkon(結婚, getting married).
The Ayaya scene. See here. This one scene has spawned numerous memes since the anime premiered in 2013.
Even the Ayaya face has become a meme, resurfacing in 2017 on Twitch TV. Fans of the show made a FrankerFaceZ emote for Twitch, and it has since become one of the top 15 emotes in channel usage as of October 2018. Of course, individual Twitch channels took notice and since then it has become one of the most popular paid emote variations on the entire site, with over a hundred variations that artists had made for streamers to use.
Watching AYAYA for 10 whole hours, usually as a bet or subscriber goal on Twitch.

JoJo fans who watch Kiniro Mosaic quickly started cracking jokes about how Karen Kujo is related to Jotaro Kujo. Aside from the name, it helps that they're both part-British on their mothers' sides, part-Japanese on their fathers' sides, and their families are both wealthy. Karen even tries out the delinquent style (which Jotaro represents fairly well) on a couple of occasions.
Surprisingly Improved Sequel: The consensus is that Hello! is a huge improvement on the first season, building on the already-established characters and their interpersonal relationships, and what's more, seamlessly adding in new characters that the existing cast bounce off well (see Kuzehashi and Honoka for Karen).
Sweet Dreams Fuel: The show is very fun and relaxing, just the thing needed after a stressful day at work or school.
