Angst? What Angst?: At the end of 'Nimrods Are Forever', Space Guy accidentally activated his Ultimate Nulifier and wipes out everything and everyone except for himself, Nash, Arlo, and Stick Boy. The four take the fact that everyone they know is dead and they are the sole survivors of the entire universe...very well, actually. Possibly justified given how things go right back to normal in the next episode.
Archive Panic: The live show has been running almost every single week for close to seven years, with episodes running from thirty minutes to an hour, totaling somewhere over 300 episodes as of March 2017.
Additionally, his use of "Doctorin' the Tardis" by The Timelords when he has to explain back-story. Sometimes he uses "Doctor Who on Holiday" a mashup between "Doctorin' the Tardis" and Green Day's "Holiday" from the American Edit mashup album.
In fact, Nash has a knack for choosing appropriate music for the situation at hand, which is understandable given his line of work. A crowning example of this would be in his Top Classic Doctors review, where he managed to choose perfect songs to represent each Doctor.
The intro to Here There Be Dragons features a chiptune cover of Gary Moore's "Over the Hills and Far Away."
Crazy Awesome: William Todd from "Walmart Chemical Warfare," a man who committed 11 felonies in Nashville, Tennessee. Including, but not limited to, jacking a Slaughterhouse (a gun shop), two cabbies, four people leaving a bar, a Canadian couple and ransacking a law firm. All in NINE HOURS. It's the frickin' Real LifeGrand Theft Auto!
Also, Arlo. He's crazy, but he's a crazy genius.
Ensemble Darkhorse: Disembodied Orgasm Hippo, a rather creepy hippo toy Tara has and frequently shows off.
Bridget, the cat that now currently lives with Tara is becoming even more popular, to the point that Tara jokes that nobody cares about her any more and just wants to see the cat.
The cat that Tara lived with, Miracle, for her crankiness and utter refusal to acknowledge the camera. They called her "Kitty-Gives-No-Fucks."
Whenever a chat participant gets their pun spoken out loud by Nash during the show, they become sort of one in the chatroom.
Peggy and Dottie, Tara and Dan's new kittens. Dan also counts, as whenever he shows up or comments, it's always funny.
Fridge Horror: The show has an absolutely colossal number of stories where people go insane for any number of reasons and attack or harass random strangers, often out of nowhere and without provocation. As cliche as it sounds, it could happen to anyone.
Especially since there's really no way to prepare for that level of batshit crazy. You can take martial arts classes to learn how to defend yourself from a mugger, but there's no classes on how to deal with a crazy naked guy on bath salts who's clinging onto the hood of your car as you drive down the freeway.
In "A Shotgun Christmas", Tara made fun of Nash for getting worried about being bitten by a Brown Recluse Spider. Several years later, she was bitten by one and had to be hospitalized.
Harsher in Hindsight: During the 12/10/12 show, they had a story where something bad happens to a child in Connecticut. There's a moment of realization for Tara that it happened in Connecticut (because she lives there) and Nash laughs at that. But for anyone watching when it was posted later, after a certain tragic event that happened in Connecticut... Nash's laugh might have seemed inappropriate. (The comments on Blip and TGWTG were quick to point this out.)
The Doctor Strange pilot review has a few jokes that can come off as this, since it co-stars Jew Wario and is one of the last videos he did before committing suicide. In particular, the review opens with Nash, Linkara, and Film Brain beating JW so severely that he spends a year in a coma, including a shot of him unmoving in a hospital bed. When Nash screened a rough cut of the review on RDA, he warned the fans that it would probably be uncomfortable to more than a few of them.
Now that the finished episode has been released, Nash begins it with a similar warning, stating that Justin wrote much of the script and that it is in keeping with the TGWTG folks usual humour, it's just that context makes parts of it... uncomfortable.
On the last show of 2013, Tara remarked that "aside from all-out nuclear war, I don't see how next year could be worse than this one." Less than four weeks into 2014, and - well, see the various posts about JewWario.
In "Red Bull Gives You Madness," there's a story about skeletons being stuffed into teddy bears. That's pretty bad on its own, but gets even worse if you're familiar with Five Nights at Freddy's, where the game's backstory implies that a murderer lured five children backstage at a Suck E. Cheese's, and stuffed their corpses into the animatronics.
In one episode they talk about a guy masturbating while driving and mention the need for a "Don't jerk and drive" campaign, a few months later note In the "Secret Nazi Gumball" episode they cover a campaign that uses that as a slogan to tell people not to jerk the wheel on icy roads.
Considering his distaste for the fandom surrounding My Little Pony, no one would have ever expected him to dress in a pastel pony one-piece costume for Halloween 2016. (He does excuse it by explaining that he wanted to scare the parents rather than the kids.)
Ho Yay: After the very long break between pre-taped episodes, Space Guy is seen singing "Stand By Your Man".
Just Here for Godzilla: There's a large portion of the viewership of Radio Dead Air that are only there for live WTFWWY, to the point where asking when it will start in the chat before its 11:30PM US Eastern start is now apart of the Drinking Game the regulars have. The regulars also enjoy lightly riffing about the "mass exodus" of people leaving the chat immediately once the show is done (some even leave before the sum-up is over).
Some new users that come only for WTFIWWY are often dismayed that 90% of RDA is music (primarily requests that skew towards the Alternative Rock side of things) and make their point of airing their dissatisfaction with this as loud as they can. These people are usually banned before WTF even starts. Bans are also a part of the Drinking Game.
Memetic Badass: Colonel Igor Koslov, Savior of ERF. During Nash's New Year's Eve 'Iron Man' note (limited to a single save file that continuously overwrites itself) play-through of XCOM: Enemy Within, he hired a rookie Russian Assault-class with big ambitions. (Nash immediately took a liking to him solely based on his name) Being one of the only soldiers to live all the way through, start-to-end, his exploits grew from impressive-but-typical to deific in short order.
Even months later, Igor's still one of these. Nash's playthrough of XCOM 2 had the chat note that X-Com lost the war because they failed to recruit Igor in that timeline, and after being badgered by the chat Nash added an Igor Koslov to his RimWorld game.
Never Live It Down: The audience have been reminding him to hit "record" (whether he needed it or not) since he forgot on 5/21/12.
Some Anvils Need to Be Dropped: WTFIWWY may tend to feel a bit Anvilicious at times, since Nash and Tara will often repeat certain morals multiple times throughout an episode... But it's completely justified because most of those morals are things that should be common knowledge or common sense. However, the staggering amount of idiots who do stupid or dangerous things proves that, yes, those morals bear repeating.
Squick: The stories featured on the show tend to be... kind of gross at best, and absolutely horrifying at worst.
Taken Up to Eleven when somebody has sex with a dead squid. Which, as theorised by Nash, will spawn CTHULHU.
One very notable example was when the story was about a guy with his dick caught in a toaster, and the article had a list of all the other weird 'person gets body part stuck in thing' stories. Both Nash and Kyle were horrified when the article said that there had been five instances of people with their hands caught in shredders, and Kyle looked like he was going to throw up for a minute.
Two words: Nose maggots. Thankfully, this later turned out to be fake.
In fall 2014, Tara was briefly hospitalized for a spider bite that had ended up turning necrotic, as well as her later testing positive for MRSA. The medical care left a hole in her leg that has become, according to Nash, "almost a character on [the] show" due to Tara's descriptions of it. Those descriptions are, to say the least, rather gross.
The 12/1/2014 show's last story: man boils My Little Pony doll in jar of his own semen.
Too Soon: The reason Nash temporarily retired the Douchequake after the earthquake/tsunami in Japan.
Nash himself following him losing his job and he and Hope breaking up in the same week. Seriously, the guy looks like he needs more hugs and puppies then Doug does when he's depressed. Some fans have noted that 2013 just sucks for the guy.
Especially since he's now suffering from insomnia.
