Twilight Princess: Malo from has telekinetic powers, Colin is hated by his parents, Purlo wants to steal Link's virginity, Falbi wants Link to molest him, and Yeto the yeti likes shoving people for giving him soup ingredients and is also very religious.
The Freezards in Snowpeak Ruins aren't blocking a spiral staircase; they're just really amazed by walls.
"Every time I wake up, it just gets BETTER!!!"
Bomberman Generation: The boss of Tako Desert is a Charabomb Merge Gone Horribly Wrong, and therefore wants to get rid of any future merges. Ein is also desperate for Bomberman's company.
Skyward Sword: Dumple (Link) is a crazy psychopath.
Ni no Kuni:
Drippy is made into the worst and most insufferable punster.
Thorn's opinion of the game is occasionally brought up as the LP goes on. He defends it heartily at the beginning, just about hates it when the game is finished.
Dragon Road has no dragons, just flying knives. The next time flying knives are encountered, Travis insists that they are dragons.
Thorn suggests early in the LP that he and Travis should write lyrics for "Redial". When the song is requested by the Something Awful thread for a montage video near the end of the LP, they do exactly that.
During the Lanayru Sand Sea, Thorn and Travis start talking about the to-be-Let's Played Ni No Kuni, namely how often Swaine dies in battle. Later when Thorn kills the Moldarach miniboss, Travis yells out Swaine's death cry.
During Skyward Sword, Thorn talks about how he thinks the game is tedious and annoying in hindsight, after a first playthrough, but still a good game.
But not so mercifully applied to Bomberman Hero and Bomberman Jetters. Let's Playing both games made Thorn go from liking them to hating them. He'd already assumed the same would happen with Bomberman Generation before he even started playing.
Brown Note: Just the sound of Thorn's kazoo or Travis' tuba mouthpiece is enough to send the whole trio into hysterics. When Travis brings the latter out at the end of Day 5 in Pikmin 2:
As recently as Shadow of the Colossus, Pibot still finds his way into the discussion.
Calling Your Attacks: Thorn and Yoshi note that the Grand Bomber can not do this with any accuracy or cohesion.
Canada, Eh?: Or as Travis calls it, "Cananada Land", because it irritates his Canadian friends.
Canon Discontinuity: Every LP from before Bomberman Hero has been removed from TheStrawhatNO's YouTube channel or set to private/unlisted. Solidified when Thorn updated all of the LP playlists, and Bomberman Hero is listed as LP #1.
"[X], everybody!": Whenever they realize something particularly screwed up has happened, namely in Twilight Princess. Can also be "TheStrawhatNO, everybody!" when they've been saying even more ridiculous things than usual for the past few minutes.
Travis gets special mention. The main reason Thorn invited him to co-commentate Bomberman Hero is because of how quickly he comes up with ridiculous things to say.
"Did you forget how abstract I am?"
Travis points out in Shadow of the Colossus how there is always at least one character in every Let's Play that they make insane or creepy. These include Agro, Pibot, Fi, the President, and every other NPC in Twilight Princess.
Cluster F-Bomb: The captions in the Bomberman Generation collection video when it gets to Eagle Bomber.
Most of the love letter sidequest in Skyward Sword is spent laughing at Cawlin's misfortune.
Thorn (As Dumple): "I'm gonna sit here and laugh at you! Ha! Ha-ha!"
Travis (Also as Dumple): "So tell me how you feel, 'cause I don't care!"
The entire Sleeping DogsLet's Play is this. Travis causes more than a ridiculous amount of pain, murder and destruction to the citizens of Hong Kong (innocent and otherwise), and the trio spend the whole time cracking up over it.
Dissonant Serenity: Bomberman's idle animation in Generation is him dancing in place. It makes for some very blatant dissonance after almost every boss fight, and the guys lampshade the hell out of it.
The ending of Bomberman Hero not only has such low graphical quality that the other Bomber characters are just jumping statues, but there are so many of them that the framerate drops.
While Thorn is fighting The Imprisoned the second time, he fails to jump on its back and instead hurts himself. He switches to Groose to attempt to slow the monster down, but the bomb flies right through The Imprisoned's hair.
Travis: "The old woman at the top just facepalms."
Fan Nickname: Invoked. Thorn let the Something Awful thread suggest names for Link and Epona in Twilight Princess. The trio decided on Hey Hey and Pibot, respectively. They also named Skyward Sword's Link "Dumple" and his Crimson Loftwing "Hambagular".
Fantastic Racism: Thorn points out to Yoshi that the Jetters were willing to kill all the Hige, even the ones who aren't doing anything.
Yoshi: THE ENEMIES ARE HAVING FUN! NOT ON MY WATCH!
Foreshadowing: On Day 4 of Pikmin 2, Travis jokes "Happy early St. Patrick's Day. I'm already drunk". Then on Day 7, Yoshi says "Travis, you're drunk, go home!" Then comes Day 9, where Thorn and Travis are drinking for the first 50-75% of the video.
Travis: "No wonder they went into debt! They have no sense of value!"
Fridge Logic: In-Universe, they point out odd placements for treasure in Pikmin 2, such as measuring cups and false teeth in a shower room. In addition to the irony of more food treasures existing in the Submerged Castle than in the Glutton's Kitchen.
Travis also questions why he's still bringing logic into the game, right as a kamikaze spider appears.
Yoshi: "Why?! Look at the spider bomb! Look at the spider bomb!"
Grand Unifying Guesses: Travis starts a round of this, with everyone connecting Pibot with the Temple of Time and Pikmin.
God-Mode Sue: Parodied in-universe with the Purple Pikmin. Not only are they Game Breakers in Pikmin 2, but now they can fire black holes, and control space and time. Not to mention finding seven cures for cancer. And causing five more.
Heroes Love Dogs: Zig-zagged with Thorn. Considers himself a dog lover and is as subject to Cuteness Proximity as anyone else during the LPs, but he is somewhat infamous for losing his temper to the dogs outside his house.
Mistaken for Racist: Invoked when Travis and Thorn talk to Gondo about repairing Scrapper, and everything they say as Dumple is a desperate attempt to not sound racist while saying something pretty clearly racist.
Mondegreen: Non-music example. Uncut versions of Twilight Princess videos sometimes include subtitles, which read out what Thorn thinks Minda's gibberish could be saying. Travis also started doing this during the commentary.
"Rick" is originally used as a Scapegoat Creator, the one guy in every development team who comes up with the bad ideas, and every time it's the exact same Rick. In some cases however it's a name the guys use to denote a random Jerk Ass.
Several character names reappear in later LPs, such as Dumple and Pibot. PizzaJoe was also used for two Zelda LPs going on at the same time.
Physical God: After exploiting a glitch in Twilight Princess where Link can "kill" the Postman, he comes back (part of the glitch), and from then on he's mentioned as warping space and time and flying in any future chasms that Link crosses.
Travis (as a very playful Midna to Wolf Link): "Would you like a tickle on the booty-boot?" He later says he never said "booty-boot" before.
Redundant says this of Epee Em's "Hey, Hitler-head!" when talking about Ashei's hair, which looks like a toothbrush mustache on her forehead.
Travis when Fyer repairs the Sky Cannon: "Words I never thought I'd say: 'clown repair montage'".
Thorn describes Constructor-X as "awesome but embarrassing". Redundant notes that more things should be described as such.
Ni no Kuni:
Thorn: "Certain ingredients can only be bought from Hootenanny. And I can't believe I just said that."
Then again when he mentions the "Cawtermaster".
When discussing the multiple tiers of Familiar food:
Travis while laughing: "That's such an odd statement. 'Sweetie Pie, the next generation of pie!'"
Retsupurae: The channel's primary videos for the first year or so before Thorn and Yoshi returned to Let's Plays. As of 2012, they no longer do Retsupuraes, and many of them have been set to Unlisted or deleted. The links for all of the RPs can be found on their site.
At one point they even Retsupurae two of former teammate Fatman's Retsupuraes. Most of the video comments involve the word "Inception", naturally.
Everything in every game is frustrated. Even the player is frustrated.
"I look ridiculous!"
Travis and Thorn reference "500 Miles" by The Proclaimers almost every LP.
Whenever something cool happens, Travis shouts out "America!"
Every bad design choice (starting with Bomberman Hero, then later every game Thorn and Yoshi play) was by a nerdy developer on a pizza high named Rick, and every trolling moment made in a Nintendo game is direct result of Shigeru Miyamoto.
Whenever Thorn or Travis suggest a good gameplay mechanic, Yoshi says, "Whoa whoa, let's save that for [next game in the series]."
The ridiculous voice acting. Max, Birdy, and Gangu are favorite mockery targets.
Shout's ridiculously useless or repetitive advice.
The Jetters, rather than being an intergalactic police force who wish to bring peace, are a bunch of jerks who are doing this mission, not to save Planet Bomber, but to punish the Hige Hige Bandits for having fun.
The effect having a hero named "Dumple" would have on everyone, including Dumple himself.
When Thorn is joined by Yoshi, Dumple is the LP's resident insane character. When he is joined by Travis, Fi becomes this.
Whenever Thorn finds a Monster Horn in a treasure chest, he sarcastically says "'Cause you know..." to emphasize the pointlessness of stashing one of them. Twice they appeared with so much frequency that he exasperatedly yelled out "Why?!"
Thorn and Travis are both music buffs and have sang/namechecked Nick Cave, The Proclaimers, Motorhead, and a lot more during various LPs. They reference The Proclaimers' "500 Miles" so often it's turned into a running gag.
Travis and Thorn's assessment of the signature TheStrawhatNO sense of humor boils down to this trope, after the two alternate (almost immediately) from DaVinci helicopter jokes to cocaine jokes in Shadow of the Colossus.
Thorn: "We're like the dynamic range of an orchestra: we go all the way up and all the way down."
Travis: "We can somehow fit into one sentence 'Pavlov's conditioning, motherfucker', and it somehow works."
From the first screenshot update for Ni no Kuni:
Thorn: "Since nobody said if they actually give a shit if I transcribe the dialogue, I have forgone the minutia."
Soundtrack Dissonance: Travis likes to invoke this while driving vehicles in Sleeping Dogs by switching to the classical music radio station, especially if something ridiculous is happening. It makes even dorky scooters and chicken trucks seem awesome.
So What Do We Do Now?: Travis jokes that a dice-like enemy in P2A2 of Bomberman Hero has the aspirations to one day roll a 6, and when it does, it thinks, "...Well now what?"
Squee: Thorn lets one out after gaining control of a statue in the Temple of Time in Twilight Princess.
The Burrowing Snagret in the Valley of Repose, dropping an Ultra Bitter Spray just outside of where Yoshi/Olimar would be able to reach.
Thorn: A person in the Twilight Princess thread requested that he do a live commentary version of the Cave of Ordeals so that they could hear his frustrated reactions as they happen. Thorn does exactly that...and proceeds to speedrun the cave using a debug glitch that was accidentally left in the game.
"These guys right here (the Hige Higes) have 50x more personality than all of the Jetters combined, and 100x more charm... These guys have been placed on a planet that, let's remember, is flying to another planet to destroy it. The entire Hige Hige fleet is on this planet to die! ... Mujoe and Mechadoc are the biggest assholes."
Younger than They Look: Thorn, Yoshi, and JelloApocalypse joke that Professor Ein is actually fourteen, even though he looks like an old man.
"Allow me to hold you in my silver, human-killing arms."
