"Saten: "So Haruhi san, tell me which side of a chocolate cornet do you eat first?"

 * Finger-Poke of Doom: Haruhi is able to bypass Accelerator's powers and flick him in the nose.

 * Idol Singer: Haruhi becomes the talk of Academy City after an impromptu performance. She does have the voice of God, after all.
 * Rescue Romance: When Kyon rescues she instantly crushes lusts after him, much to his annoyance horror.
 * Schroedingers Cat: Thanks to Haruhi's subconscious Reality Warper powers, when asked to guess a card randomly drawn from a deck, she can guess a card that isn't in the deck and get it right. Some observers describe this as if someone did the Schroedingers Cat experiment... and pulled a dog out of the box.
 * Shout-Out:

Mugino: "Mugi chan she says… what am I some kind of moeblob now? My eyebrows are perfect damn it!"

Haruhi: "You know what they say Capitalism, Ho!""

""Mind if I ask something… how did you saw all that stuff?""
 * Kyon says that Kanzaki and Nagato carved "a weird circle that looked like something out of that alchemist manga that ended recently."
 * The scene where Index was visiting Touma in the hospital while eating melon bread, and eventually offering one to Touma reminds one of a certain blazing Tsundere.

 * Wham! Episode: Chapter 11. The SOS Brigade.
 * Wham! Line: You know the first line Haruhi spoke in the original source? She says it again...!!
 * In Chapter 18, Aleister receives a phone call:
 * What the Hell, Hero?: Tsuchimakaido receives this from nearly everyone else for telling Aleister about Haruhi in the first place just so he could have a bargaining chip to legalize marriage between Not Blood Siblings. Hell, even Aleister calls him on it.
 * What the Hell, Hero?: Tsuchimakaido receives this from nearly everyone else for telling Aleister about Haruhi in the first place just so he could have a bargaining chip to legalize marriage between Not Blood Siblings. Hell, even Aleister calls him on it.
