* Almost anything involving Joachim and Harvey. Their bickering is absolutely hilarious, especially Joachim's attempts to hit on Kieli in book 8.
* Harvey's possessed robotic arm in Vol. 2. If he's being mean to Kieli, it either disobeys him or even downright tries to punch him in the face.
* The Corporal's reactions any time [[spoiler:Harvey and Kieli are having a romantic moment.]] The funniest instance is Vol. 8, when [[spoiler:Harvey and Kieli finally kiss.]] By this time, the Corporal can't actually talk, only making hisses of static. Kieli flops part of her skirt overtop of him to shut him up...or rather, dull the noise.
* Harvey realizing in Vol. 8 that he can't weasel his way out of [[spoiler:kissing Kieli]] this time.
