- The Big-Lipped Alligator Moment (which is Kouchi's Imagine Spot) during Episode 6- during a class exercise in which none of the students are allowed to move or speak, the two of them dance together in front of the class, since both of them are "non-existent" and no one is supposed to acknowledge their presence. That spells out what the audience think they will do if they were in his shoes. Doubly funny due to the nature of the rest of the show.
- Speaking of which, Kouichi's facial expression when the scene cuts back to reality.
- Episode 8 is pretty funny being a Breather Episode. Until the end.
- The class splits into teams, Mei and Kouichi's side are dubbed The "Non-Existent team".
- Akazawa ends up with a HUGE pile of kelp landing on her head.
- Mei getting panicky thinking a little octopus that had attached itself to her forearm might try to eat her.
- Let's not forget Mochizuki buried under a huge mound of sand complete with impossibly (impressively?) aerodynamic breasts.
- Episode 2 had a funny moment in an otherwise Uncanny Valley setting. Kouichi visits the doll shop for the first time and sees the doll that resembles Mei. The doll "speaks" to him, obviously freaking him out, but it turns out to just be Mei standing behind the display. What makes this more funny, was that he thought Mei was actually a doll to begin with.
- The exchange between Mei and Teshigawara after Kubodera kills himself.Teshigawara: You really are weird Misaki. You talk like this doesn't involve you. It doesn't make any sense.Mei: Do I?Teshigawara: Could it be that you're actually the extra this year? Ever thought about that?Mei: No but it could very well be you, you know.Teshigawara: Me? No way, don't even joke about that.Mei: There's really no way?Teshigawara: NO NO NOOOO!!!! I have no memories of dying. And not to brag, but I remember all the shit I got into as a kid.
- The ferris wheel scene from the OVA. It starts with high dramatic tension with Misaki Fujioka dangling from the ledge, before finally having to be let go... And end in pure Bathos as she was already safely on ground level by the time she let go.
- An unintentionally hilarious moment happens in the live-action movie, during the scene in which Sakakibara's introducing himself to his classmates. The rest of the class gives him unpleasant looks... except for one of the boys, who has a goofy smile on his face, as if he missed the memo on how his character's supposed to act in that scene.
