Fukuda is riding his motorcycle against the setting sun, out to get Nakai for being a jerk to Aoki. He suddenly realizes he has no idea where he is going.
Shuujin: "I WANT TO BE POPULAR!"
The entire chapter where Mashiro and Takagi trail Hattori in disguise.
When Kaya finds out Takagi can touch type he shows (off screen) the other things he can do without looking.
Early on, when Mashiro and Takagi find out that "Money and Intelligence" ranked third and believe they cannot make first place with a cult hit, dramatically throw their manuscripts in the river. They then realize how environmentally unfriendly it would be, and then flee the scene before someone sees them.
Shiratori's first few days living on his own, particularly when he tries to do his own laundry and cook his own food.

As noted under the Asleep in Class entry on the main page, most of the time when Mashiro and Takagi sleep in class, they're catching up on sleep. The exception is when Mashiro falls asleep during a test, and his reaction is quite funny to watch, especially his line reflecting on it.
Mashiro: Sigh... I bet Azuki and the others thought I must have studied real hard for the exam... They're going to think I'm an absolute idiot once they find out I completely failed it.
Kaya walking in on Takagi apparently doing a handstand to cure his writer's block.
Takagi: I-I can't come up with any ideas...even if I do a handstand...
Kaya: How would that help...?
Miho's Christmas song (season 2, episode 24) is actually a hearwearming moment, but you can't blame yourself for laughing about her Gratuitous English.
