Funny: K-On!

  • Moe Moe Kyun~! That is all. (S1 04 14:55)
  • The time where after a long practice with Sawako-sensei, Yui lost her voice. (S1 05 21:19). Thanks to Sawako, she can play and sing at the same time, but sprained her voice in the process. Now Mio has to sing. "Do it for Husky Yui!"
    • The part of episode 5 where the characters start acting like they're in a mystery manga.
    • This pays dividends in episode 6 where Mio does lead vocals for "Fuwa Fuwa Time" but Yui still provides backup vocals...with her hoarse voice.
  • Mugi "bargaining" with the music store clerk - who, by the way, recognizes her immediately as the daughter of the shop's owner - to get a discount on the guitar. Lower! (S1 02 18:10)
  • Sawako-sensei trying to punish Yui by making her wear an embarrassing Santa outfit, only for it to backfire when Yui proves to have no sense of shame. (S1 07 13:50)
  • Jakka jakka jan jan jakka jan! JAKKA JAN! (S2 03 14:00)
  • Sawako-sensei briefly fantasizes about a masked Ritsu playing epic death metal beats at the foot of the TOWER OF BABEL.
  • Ritsu eating the reciept in front of Sawako-sensei while the rest of the band chants "Swallow! Swallow!" (S2 02 17:29)
  • Mio's infamous Panty Shot. (S1 06 20:54)
  • Tiny little Azunyan dragging YUI crying and screaming by the collar off the study in Season 2 Episode 9.
  • Another one: Mio finally giving in to Sawa-chan's hobby.
  • Season 2, Episode 14 In an attempt to get hit in the forehead, Mugi tries stealing the one strawberry atop Mio's slice of cake. Just... watch. (S2 14 19:02)
  • Several moments in episode 18 of season 2, as if the plot for that — Mio and Ritsu trying to play against type — wasn't enough.
    • "She fainted..."
    • Mio's Freak Out in the beginning, complete with her listing reasons she can't be in the play that get more outlandish with each one, is pretty funny- and then the camera angle changes, revealing that Yui has been holding her arms like a tree the entire time.
    • Mugi suggests to Mio that she should pretend Ritsu is the only one watching her. Mio looks out at the girls and imagines that they all have Ritsu's face.
    "That'd get noisy real fast..."
  • The show starts of hilariously with the first episode of the first season, when the girls try to convince Yui to join their club. In no time the club room changes into nothing less than a war zone, complete with emotional close-ups of all involved. That scene's punch line ("You guys are really not that great") is very funny as well.
    • There was also that scene a dozen minutes prior to that when Ritsu asked if The Promise Mio made was a lie. Her response? "That entire flashback is a lie"
  • The moment in Season 2, Episode 14, when Mugi finally gets her wish and has Ritsu club her over the head. What it took? Of course, telling Ritsu that she would make a great boyfriend.
  • "Aren't waitresses supposed to have cat ears?"
    • And from the same episode, Azusa sounding like all four of her seniors on her way to the club room.
  • Omochi Race. That is all.
    • "WAA WA WA"
  • Azusa imagining herself as club president.
  • Nodoka stopping Yui from eating a crayon on the first day they met.
  • Season 1 episode 3. PUNI PUNI!!!.
  • The whole affair with Yui cutting her bangs. Without a mirror.
  • The whole exchange between Yui and college K-On member Akira.
  • On the first day of their senior year, Ui decides change her look exactly like Yui. She then plays up the joke by saying that she really is Yui ("I wanted to see Azu-nyan and came here pretending to be Ui!")...and Azusa starts believing her.
    • Ui regrets doing that when Sawako starts talking to her chest, which Sawako has already noticed is bigger than her older sister's from the first time Ui did that.
  • The fact that Azusa can't sing
  • The new highschool Light music club member Okuda somehow makes Yui seem like a genius.
    • It's discovered that she's been inadvertently giving people parts that require three hands or six fingers to play right. This doesn't stop Ui from playing it perfectly. (No, she does not have six fingers.)
  • Chapter 61. Just make sure that you are in a soundproof room as to not disturb anyone.
  • One chapter of the Highschool spinoff starts with Azusa announcing that she's going to run a tight ship, practice hard, and really impress Yui with how great the new club's band is going to be (now that they have enough members). She then walks into the room to find Sumire in a maid outfit serving tea to Sawako.
  • Azusa wants to rub Sumire's head, remembering Mio doing it to her. Unfortunately, not enough words — or too many — slip out, and it backfires...
    Azusa: No, not me!
