* Pretty much every interaction between Shirou and his sister. Actually, we might just go and say every scene which has Yukari in it
* [[ItMakesSenseInContext "Ah.]] [[RunningGag I forgot."]]
* While trying to create a cover story to explain the damage caused by Homura's winging, Shirou give Shinji's name as his own.
* Shirou's reaction towards the...ahem...clothes his sister bought for Akitsu. Made funnier with each repetition.
** Made even funnier when it happens in the presence of witnesses
-->Landlord (upon seeing one of the exhibits): "W-w-what was that t-t-thing?"\\
Shirou: "One of those things a man should not be nearby when his girlfriends are packing them"
* TheInternetIsForPorn. That is all.
* Shirou's reaction upon finding out [[spoiler: his mother is one of Homura's most prominent customers]], along with the subsequent scene
* "Kuu-chan also wants onii-chan's babies!"
* "You're a Tsundere!"
** Homura nearly loses it when he realizes how right Shirou is, too.
* [[HardDrinkingPartyGirl Kazehana]] doing, as Matsu put it: "The legendary NakedApron!"
* Shirou reading the message from Minaka in chapter 5.
--> '''Shirou''': "[[{{Emoticon}} Colon. Parenthesis]]."
* Yukari's departure from Izumo House in [[MoodWhiplash Chapter]] [[WhamEpisode 24]]:
-->"Wait, Yukari," I called as she disappeared out the door of the dining room. "At least show up on weekends," I yelled, hoping for at least this mercy. "I'll make your favorite teriyaki!"\\
"Okay, rival-onii-chan," she called back happily. "I'm off to fight the forces of evil! See you on Saturday!"\\
"There has got to be something wrong with that girl," I muttered, unable to believe what I had just seen. "Takami must have dropped her on her head a few times when she was a baby."
* Homura's reaction to learning Saber was King Arthur.
--> '''Homura''': "And you were boinking him!"
* This bit from Chapter 21, after Miya finds Shirou in a NotWhatItLooksLike scenario:
-->"So that's what happened," Miya said, sounding like she was waffling between amusement and resignation. Putting one hand to her chin she turned to look away, muffling her voice slightly as she continued. "And here I thought Emiya-kun had just finally succumbed to his primal carnal urges."\\
I gave her a small glare as I finished ladling the miso soup into the bowl I had set before the landlady. "'My primal carnal urges?'" I repeated in an aggrieved voice. Miya nodded, her face the picture of innocence as she continued to tease me.\\
"After so long restraining yourself, I had wondered when you'd finally give into your baser instincts and ravage all the beautiful women around you," she informed me. She put both hands to her cheeks and looked to the ceiling. "Ah, and me, an innocent widow. What would my dear husband think if he knew that I was near such a beast?"\\
"'That poor, unsuspecting beast'?"
* Seo gets called by [[spoiler:Yukari in the middle of his match at the beginning of the third stage.]] It distracts him long enough for [[spoiler:Sanada]] to punch him. When he finally answers it at the end, he gets into an argument with [[spoiler:her about he isn't going to give a speech about love and justice.]]
* Matsu summing up {{Nasuverse}}!Earth's inner workings:
-->"The Earth is alive, it has a split personality, and [[EverythingIsTryingToKillYou it's trying to kill]] [[GaiasVengeance everyone]]?"
* [[LiteralMinded Literal]] FogOfWar, with many fog machines in the battleground. Shirou wasn't amused.
* FunnyAfro Miya.
-->Even more surprising was the state of her hair. It had been blown back, as though by some great wind, and even more unusual was the way it was somehow maintaining that position, crinkles of what looked like a static charge keeping her long lavender mane floating about her head like some sort of enormous light purple afro.
* The idea of Miya simultaneously teasing and (in all honesty) advising Shirou about learning [[http://en.wikipedia.org/wiki/Hoj%C5%8Djutsu Hojoujutsu]] ({{TOW}}: traditional Japanese martial art of restraining a person using cord or rope) to prevent [[DoesNotKnowHerOwnStrength accidents]] like the one during [[TheirFirstTime his first time with Akitsu]] from occurring is at least giggle-worthy, but the way how Shirou caught her [[SayingTooMuch poor choice of words]] and drew his own conclusions about [[CovertPervert her]] is just hilarious. It went more or less like this:
-->'''Shirou:''' "Wait a second. It's mostly called 'shibari' these days. How did you know the old fashioned name?"\\
'''Miya:''' (looks away innocently)\\
'''Shirou:''' "Hold on. I know that you tend to favor traditional methods of doing things. Don't tell me you and Takehito…"\\
'''Miya:''' "Shirou, You shouldn't imply such things to a young widow!" (hands over a platter) "[[ChangeTheUncomfortableSubject Now go and take this out to the party immediately!]]"\\
'''Shirou:''' "Oh, I see. It's alright to say whatever you like about my sex life, but the moment yours comes up…"\\
(sound of steel being drawn)\\
'''Shirou:''' (flees)
* The Thirty-Fifth Wing, Uzume, Kazehana and Shirou all start teasing Miya about her blocking all attempts at intimacy at the Izumo Inn and eventually Miya has enough [[spoiler:however, when she tries to bring out her [[DemonHead Hannya Mask]] it fizzles. She has no idea what happened until she looks at Shirou, who proclaims that he's glad he finally got that to work. Uzume was so impressed that she started to congratulate him on it and Miya tried to use her mask on Uzume again, only for it to fail. She then stomped her foot and pouted at Shirou in a honest-to-goodness "please stop teasing me" reaction. It was either hilarious, or as [[OnlySaneMan Homura]] put it, "the most disturbing thing I've ever seen, ever".]]
* The ending of the Thirty-Eighth Wing[[spoiler:, Rin Tohsaka and Saber's arrival at Izumo House.]] Shirou is screwed.
* The Thirty-Ninth Wing. [[UpToEleven OH BOY!]] [[spoiler:Tensions build up between Shirou's Flock and his ex-girlfriends Rin Tousaka and Saber only to be stopped by Miya, Homura wanting an autograph of KingArthur (Saber), Rin's reaction to both Miya's DemonHead and Shirou's Magical Washing Machine, [[HopelessWithTech her failure to comprehend technology]], and Matsu being Matsu.]]
* As heart wrenching as the Forty-First Wing was, Shirou [[spoiler: hitting Karasuba in the face with his severed arm]] was still pretty funny. The fact that she's completely bewildered by it as well just makes it even better.
* Although a certain reveal makes the Forty-Second Wing '''[[WhamEpisode deadly serious]]''' it was really amusing that [[spoiler:Matsu created porno of Shirou (with close-ups, professional editing and soundtrack composed by herself) and the man in question just found out about it.]]
* How [[CoolVersusAwesome Karasuba vs Shirou]] ended in the Forty-Third Wing. [[spoiler:Karasuba forcefully winged Shirou once he broke her contract using Rule Breaker. The fighting stopped right away and just about every single Sekirei '''ran''' because of fear of him NTR'ing them.]]
* "Onii-chan has ''all'' the swords!"
** Really, the reactions of each of Shirou's Sekirei to [[spoiler: Unlimited Blade Works]] are pretty funny.
* The final chapter. [[spoiler: An almost 18-year-old Kusano continuously tries to seduce Shirou, with no success. He keeps telling her to wait for her birthday, which is a week away, much to her consternation.]]
** [[spoiler: The way Kazehana revealed both of her pregnancies is just hilarious. She proudly announced both of them while Takami had come for dinner, then would go on to describe the tryst that she believed led to the pregnancy in vivid detail. The second time, she even came with a tape recorder!]]
