Funny / Shakugan no Shana

  • During episode 5 of season 2, Shana comes home to find smoke running along the ceiling. Understandably she thinks they are under attack, only to find that its the result of Wilhelimina's cooking attempt. Not particularly funny on its own, but what really sells it is the battle music that starts playing just as Shana walks through the door, only to abruptly cut off as she discovers what's happening.
  • Season 2, Episode 22: The writers have some fun when Shana discovers that Yuji is getting a younger sibling. She promptly asks where babies come from. From Yuji, Yuji's parents, and then of Yoshida. Yoshida glances at Alastor:
    Alastor: "Please don't make me do it!"
    • Fridge Brillance: Shana's been training as a Flame Haze since she was a young child. Human Reproduction would have never come up in her training.
  • Season 3, Episode 8 ("The War Begins"): Two low-level Denizens are patrolling the hallways of the Star of Darkness. One of them complains about how all of their compatriots are out fighting in a war, then remarks that their enemies aren't going to just show up in the middle of the hallway… only for Khamsin and Rebecca to make their presence known by the latter's voicing of the exact same lamentation of boredom.
