* In the pilot, Erec declares Kon a WorthyOpponent, and decides to use his [[LimitBreak ultimate attack]] to finish him off...Kon hits him with a GroinAttack in the middle of it. With ''spiked boots''. Episode two reveals that he had to have ''one of his nuts removed!'' His being "off-balance" the entire episode becomes a RunningGag, and when Kon realizes what's happened, he decides to fix things by PERFORMING ANOTHER [[GroinAttack GROIN ATTACK]], BUT WITH A ''GIANT ROCKET HAMMER'' THIS TIME, hereby removing the other testicle.
* Start of the opening song contains lyrics about "becoming a man". Cue Mariandale and "Could I help?".
* Mariandale usually speaks with soft feminine voice... and sometimes she switches her voice to a much deeper tone. Kon's facefaults are more than appropriate.
** Mariandale IS the joke. Imagine [[Franchise/CodeGeass Lelouch]] in C.C.'s character avatar complete with this [[Creator/JunFukuyama seiyuu]].
* Episode 3. Kon's FreudianExcuse for not wanting to let a RidiculouslyCuteCritter into their group. He'd rescued a pair of kittens when he was a child, and spend day and night looking after them. The others are terrified, fearing the worst for what happened to the kittens, but Kon then reveals that despite all he did for them, they wound up hating him for some reason.
** Kon's rant about the animal kingdom and the survival of the fittest at the beginning of the episode features the characters giving him strange looks and ends perfectly with Mariandale saying "I have no idea what you are talking about."
* If the princess has one IdiotHair, she's a supreme BigEater. If she has [[AntennaHair two]], then she request people to do odd things. if she has '''three''', then she becomes a FRIGGING ''CHUPACABRA'' THAT CAN SCARE A [[AxeCrazy SERIAL KILLER]] STRAIGHT!
* Never mess with Mariandale while she is cooking for a princess in hyperactivity . NEVER! She WILL MESS YOU UP!
* Erec's ImagineSpot in Episode 4; "I don't need my balls to love you"
** This is followed by Emilia's petrified reaction.
* Erec's reactions to any word or statement involving the word balls.
* Near the end of episode ten when the rest of the group complains about losing their bets thanks to Kon, Alma is shown outside tearing up her ''own'' bet that she made on him.
* An enraged Kon threatens to neuter Pet and Erec so happens to be passing by.
-->'''Kon''' (to Pet): YOUR BALLS ARE MINE!!
-->'''Erec''' (covers crotch): [[BigNo Noooooooo!]]
* Both Opening and Ending themes counts. The former sings about taking away his virginity. The latter sings about his... well Erectile Dysfunction.
** in Third Ending theme, they sang about Erec's schlong.
