Any time Natsumi uses the laugh pressure point on Tsukasa, causing him to lose his composure.
In Kuuga's world, Tsukasa was a policeman and when Yashiro and the others were having a discussion, he just barge in with a blank face in front of the bosses, pouring hot water in one of the cup until it is overloaded before slowly moving to the other side while still pouring it until the hot water is was used up.
The running gag of Yusuke believing moments of Tsukasa trolling the A.R. Riders is him being a Stealth Mentor followed by Tsukasa awkwardly lying his ass off showing that he clearly wasn't.
This dialog from the Ryuki World arc. The set-up: Natsumi has been falsely accused of murder, and Tsukasa, despite making jokes about her being a cold-blooded killer, is trying to save her - except that in this world, legal cases are decided with Rider battles.
Zolda: I won't let an amateur make the verdict! She's guilty! Guilty! (fires giant shoulder cannons)
Tsukasa: Who the heck's that?!
Ren: Probably the public prosecutor.
Tsukasa: Suddenly I very much want to prove her innocence.
When Tsukasa and Yusuke find out, Tsukasa simply snarks "So she's finally done it." Yusuke nods in agreement before realizing what Tsukasa said.
A few from the Blade arc,
Tsukasa at first is displeased with his role as a chef in BOARD's kitchen and plans to quit until he learns he's getting a bonus with the exact second he decides to return punctuated with a cash register chime. TV Nihon even throw in a "$$$$$$".
In episode 9, after Tsukasa shoos the Mustuki out of the kitchen when he comes to lord his new lead Rider status over Kazuma, the demoted Ace he calls him Cheese rather then Chief with such moved respect. He does so again when Tsukasa returns the Blay Buckle to him.
During the Kabuto episodes, a Worm impersonates Tsukasa. After the real one transforms, the fake claims that Tsukasa can't hit himself (as the worm is basically a double) and pokes him in the chest. Tsukasa responds by violently smacking his copy on its forehead before punching it in the face.
The whole Den-O episodes count, starting with the whole getting possessed thing, up to the climax, where Kuuga mistakes Den-O Momotaros for the enemy, kicking him on the neck, down to the bad guy breaking character and telling them to get their acts together, finally culminating in Momotaros' and Kuuga's..."Combination Attack".
To further elaborate on Kuuga confusing Momotaros as the enemies, he jumps high up and it seems like he would deliver a rider kick to the bad guy... then it's revealed he hit Momotaros instead and the next few minutes are spent of the trio bickering with each other that the bad guy actually gets annoyed.
Also speaking of said Combination Attack, "My Finishing Move: Decade Version". It involves one of Momotaros' blades flying up and then piercing the behind of Kuuga Gouram, we even get a reaction shot of Yusuke feeling said blade pierce up his rear. If that wasn't enough, the sounds Yusuke's sounds while Momataros way of using him can be best summed up as using Kuuga Gouram as an Epic Flail, are nothing short of chuckle-worthy.
Speaking of Den-O, there's the scene in Kabuto's world where Tsukasa puts the Taros' Attack Ride cards to use...and they're all completely worthless as all they actually do is make Tsukasa spout their catchphrases.
Decade:Ore, sanjou!note I, have arrived!
TheBee:So what?
Decade:Then how about this? *changes to Gun Form* Can't hear your answer!
Gatack and ZECT Troops:But you didn't ask us anything...
To add up to the awkward feel of the scene, the Decadriver repeats each Taros' catchphrase in a heavily English-accented Japanese.
During the aforementioned Den-O episode, Tsukasa's actions allow him to change the Den-O Form Ride from the Denliner to Momotaros himself. After transforming the camera angle makes it seem like Momotaros has grown giantSuper Sentai-style... only for it to cut and show he's just regular size and thought he was giant.
In the World of Hibiki, Kiva-la decides to summon Ouja to release a very large sized Bakegani. Unfortunately for Kiva-la, she proceeds to get hit by Ouja's kanabo right into the TV screen.
Mind you, this Ouja is not the AR Ouja, but the original Ouja (in other words, Asakura himself)...
In episode 28, Amazon is getting his ass kicked...
Natsumi: "Tsukasa-kun!"
Tsukasa: "Ah." *Holds up baseball instead of change card, complete with revving sound effect.*
Den-O: *kicks Mook out of the way* Stop interrupting me, you bastard! Ore, sanjou! Man I'm the coolest.
The net spinoff videos. All of them. Decade gives henshin pose lessons, Narutaki obsesses over butts, and even the actors themselves have a hard time maintaining character in the face of the crazy goings-on.
Also in Hyper Battle DVD: Protect! The World of Televikun. Tsukasa, Yusuke, and Kaito fight over for the magazine and accidentally dropping Natsumi's cakes. Kaito immediately accused Tsukasa and Yusuke, who dropped the cakes. Natsumi find out that Kaito himself dropped the caked, and directly using her signature Secret Laughing Pressure Point to Kaito. Then she talks to the audience...
Natsumi: "Blaming someone else is the worst thing you can do."
One of the funniest bits of the Decade Net Videos has to be Narutaki reverting from being a jerkass into the little boy who worships Kamen Rider V3.
One of the segments is about Riders' weapons, which causes Narutaki to scoff that the Heisei Riders are wimps for needing weapons, unlike the Showa Riders who mostly just used Good Old Fisticuffs. Then when it turns out that the first Rider to use a weapon was the originalnote Because he stole a sword from a Shocker Mook during one battle, Narutaki praises his cleverness. Tsukasa calls him out on being a hypocrite.
Being real, the entirety of the Net Videos could fit this page, but the funniest bit has to be the Henshin Lessons, let's give them a rundown.
Ichigo's Lesson starts off with Decade meeting a divorced man, whose wife just let him, moping. Instead of trying to help him, Tsukasa tells the audience that the best way to get your divorced wife back is...by transforming into Kamen Rider Ichigo.
Amazon's Lesson is pretty funny. It opens with our unfortunate Henshin trainee: a despairing Salary Man who has just found out the technology stocks he had invested so much on have dropped to Hooverian lows. Tsukasa takes pity on the businessman, and so he teaches him that to magically fix this potential Great Depression, he has to turn into Kamen Rider Amazon. Unlike with Ichigo, however, this transformation happens to be the one Amazon did turing the first half of his run, which he used to do while naked, which leads to the businessman himself (who happens to be Narutaki, mind you) shouting "AAAAMAAAAZOOOONN" while in a loincloth, in public. Decade adds a fourth point by telling you to "be mindful of where you transform".
Ryuki's Lesson has a few funny moments. It starts with a monk trying to dispel evil spirits for no apparent reason. Tsukasa doesn't even let the man tell him why he's doing this, but apparently, the best way to deal with evil spirits is becoming Kamen Rider Ryuki. The transformation, as you know, also involves sliding your Card Deck into the V Buckle, which can be hard to do without looking. The solution? Using the power of jump cut editing, of course! Once it's done, the man transforms into Ryuki, but is immediately sent to the Mirror World. Instead of pulling him out, Decade tells him that to finish the transformation, he has to mimic Ryuki's trademark "Sha!" once transformed...and leaves him to the mercy ofKamen Rider Ryuga and Kamen Rider Ouja. Yup, that's our Tsukasa.
Den-O's Lesson deals once again with someone with a broken bone, this time, a man named Kanda Yasao has broken his foot while playing ping-pong. And the reasoning of course, to get it fixed happens to be not going to the doctor, no, it's actually...to become Kamen Rider Den-O. During the transformation, Tsukasa gets angry at Kanda for mistaking the henshin with scanning a regular train ticket and clocks him in the face, no doubt breaking his cheekbone. Plus, the poor guy lands on his broken foot. There's also his attempts at mimicking each of Decade's henshins, with a broken foot, and a crutch, which happens to be more difficult than it seems. And the ending?. Kanda succesfully heals his broken foot while transforming into Den-O's Gun Form,note which happens to be Ryutaros' preferred form. You know, the form that pertains to the hyperactive ditzy Imagin who loves dancing more than anything. Hard to believe this man can do the twirling with a broken foot. while the man's doing his purchases on a 7 Eleven. Advertisement, who?.
Wrapping this sub-series, Decade's Lesson shows us a father who's desperate due to the man accidentally purchasing a Den-O Rod Form sofubi for his son, instead of a Gatack sofubi.note in a previous Net Video where Narutaki quizzed the gang with "How could a grandma differentiate these two when purchasing Gatack for her grandson"; the answer was that Gatack was no longer in production due to Kabuto's series having ended, so this man's search was going to be fruitless anyways. Decade continues his faulty reasoning by saying that the best way to not disappoint your son with a wrong toy, is to transform into Decade himself!. Not only does the father bend the card, and can't pull all stops at once, but when he finally manages to perform it flawlessly, he transforms into a Decade...sofubi toy, complete with six inches of pure power and like three points of articulation. Instead of at least putting him, alongside the Den-O Rod sofubi, in a bag, and carrying him home, Decade gives the man the herculean task of walking back home, with the Den-O sofubi on his back.note and given this is a Sofubi, he has no leg articulation, which makes walking kind of difficult. It'll be a miracle if he makes it by the time his son's grown out of Kamen Rider.
