Equal and Opposite Attraction/Funny

• Chapter 3 has Arf break into Negi's apartment, further cementing his status as a Memetic Sex God. She ends up finding everyone's favorite chain-smoking ermine and, more importantly, a fresh new batch of his mystical chocolates. Later it's discovered that said chocolates are essentially magic Red Bull, but for Arf, they act like the best aphrodisiac ever. What follows is one long sequence of Arf dry-humping a hapless Zafira. Signum's response?

Signum: "Zafira, I think you're doing it wrong."

• • Signum also drops another punchline after Vita wakes up on the kitchen table after Hayate got some very interesting noises out of her.

Signum: "You know there is a reason why Shamal and I sleep in another room. I would have hoped you could contain your antics to one room of the house."

• Chapter 4: Negi walks in on Fate changing, and Arf lampshades her ironing-board status. Fate is not amused.
• There's another one in the Chapter 10 omake where, after reading a hacked chatroom log, Chachamaru delivers this gem:

Chachamaru: "Perhaps the meme is insinuating that Chisame-san is using some form of device in order to properly penetrate the miniature horse."

• Nanoha finally gets to test her skill against Negi. Too bad Puberty has decided to kick in, and with Negi constantly in her face, she has to revise her Badass Boast:

"I have fought demons, monsters, robots, and summons, I have faced down the darkest depths and rescued my precious ones from its grasp. There is no obstacle I cannot surpass, no foe I that can outrun my shot. I am Takamachi Nanoha, AND I AM NOT A PERVERT!"
