Noa and Asuma end up having to share a hotel room while on assignment. This clearly doesn't sit well with her, and frets over it in the furo. So she waits until she thinks Asuma's asleep before entering the room to turn in. When he "awakes" and creeps toward her futon, she's clearly expecting to be groped and braces herself for the inevitable... except he completely ignores her and goes for her snack bag, causing Noa to become outraged and clock him!
The final chase sequence, period; particularly when Tadayama goes from outrunning Asuma and the others, to being left in the dust, until he sees what's behind them! It quickly becomes a mad dash for the exit, all while Kumagami's blissfully unaware, thanks to being passed out on Hiromi's back while he and the others are running for their lives!
The episode where everyone gets plastered between : Asuma and Ohta's fight, Shinshi's rambling, and the drinking competition between Noa and Kanuka.
Shinobu: (changing subject) "So... um, would you like some tea?"
Gotoh's attempt to peek on Shinobu in while she's in the shower. After waiting a few minutes, he crawls over to the door and gently slides it open... and finds her standing there with her arms folded, clearly having expected it. His response?
Shinobu's attempt to cover the mirror over the bed! After tugging on the curtain, she crawls over to the control panel, but doesn't know which of the buttons to press. So she picks one at random causing the bed to rise off the floor and begin to spin like a merry-go-round! In her attempt to shut it off, her hand passes over all of the buttons, making the bed spin faster, and causes the lights in the room to blink on and off!
Gotoh, meanwhile, has no clue what's going on. By the time he steps out of the bath, she's got it under control, though clearly mortified by the experience!
The entirety of episode 13: "The Dungeon Again", which is a follow up to "Mystery Tour", the 38th episode of the previous series. And, like its predecessor, it's the second half that contains the funniest scenes; perhaps in the entire series! The highlights include:
must be accompanied by parent, guardian, priest or demon
Kumagami faints again!
The various traps hidden throughout the sewers, each triggered by trip wires: including a foot snare, followed by the ceiling collapsing, a Zelda-style"locked door" room (defeat all the enemies inside!), plus, arrows hidden in the walls.
Special mention goes to Asuma opening a box containing a ticking time-bomb and a simple two word message: "wrong answer", then...BOOM!
The rescue party's reaction to finding Unoyama and the other missing mechanics alive and well... eating ramen with Tadayama. Followed by Otah's reaction!
The group's excitement over finding the pearls they were after... until they realize they're not pearls... they're crocodile eggsOh sh-!
Asuma telling the group to split up in order to shake the crocs! Now there's three of 'em!
Otah: (accusative) "Shinohara, you-!"
Asuma: (running) "Bitch later! Split up and lose 'em!"
Which gets averted when he sees everybody's still behind him since they all ran the same way!
Asuma's epic faceplant at the end of the downhill segment, which ends with everyone hanging onto his legs for dear life, with the crocs waiting directly below with their gaping jaws open! ...then the pipe gives way, leading to....
The montage at the end which features Noa's swoon routine, while swimming frantically!
The conclusion: they're all still trapped in the sewers, their backs pressed against the door, with the crocs right outside, trying to get in!!
examples from the Manga
The first chapter has a brief Running Gag that has Asuma voicing concerns of Noa possibly becoming an industrial spy, after she tells him Sakaki gave her a sneak peek of the AV-98. Gotoh seems to support his suspicions as far as industrial spies are concerned, but finds it funny anyone would suspect Noa, of all people. When Asuma objects, Gotoh finds the real problem with a simple question:
Gotoh: "What's the matter, Shinohara? Unlucky at love, in the past, eh?"
While en route to their first assignment, Ota asks Gotoh why they can't simply engage the criminals they're after, rather than herding them towards the designated target area at Ueno Park. It doesn't take Gotoh long to realize what he's dealing with and responds by calling him out on it.
Gotoh: (over police radio) "Look, Ota... you want the city to go up in flames?"
He tempts fate again, when Noa lectures him about how dangerous it is to smoke near a gas line, but he ignores her and decides to light up anyway annnnd... yeah. The explosion wasn't really his fault, but Shinobu tells him to put his lighter away just the same.
Speaking of Shinobu, Gotoh trolls her by purposely leaving her division high 'n dry so his division could get the credit for apprehending the criminals. And his response when Asuma calls him out on it...?
The following day, while they're setting up the office, he sees her struggling with a stack of boxes and takes them off her hands. Just as she thinks he's being nice to her, he tells her they weren't expecting much from her anyway!
