Towards the end of the Huzzah RP, it's revealed that slowbeef and Diabetus weren't even watching a video while commentating - they were going to splice their dialogue over a random DeceasedCrab video. It works.
LuwiigiiMaster, one of the targets of parody, gets one in that he successfully trolled Retsupurae into making fun of his Stealth Parody while deliberately avoiding the Parody Retcon problem that many other targets use. The derailment that this causes for the commentary catches the crew completely off guard, and they admit that it was Actually Pretty Funny.
Speaking of that, slowbeef deserves special recognition here, for having the sheer patience and will to sit through those six hours of repetitive gameplay without spoiling a single thing, such that the best moment of the game catches Diabetus completely off guard. It also helps that slowbeef had LPed the two games long before this giving him somewhat of an advantage.
The amount of Fan-Content of the Darkseed 2 Riff deserves mention too.
According to a Gearbox developer, Darkseed 2 got a Shout-Out in Borderlands 2 (Mike Dawson is listed under the "Special Thanks" section) directly due to the duo's Wrongpurae.
When a bad LPer commends Retsupurae and acts like a good sport counts.
Alternately, whenever a bad LPer takes advice and finds a way to improve their videos.
Paul Eiding himself left a comment on their Evil Zone video, stating how hilarious he found their commentary to be:
OMG! You guys had me in stitches with your commentary. I remember them wanting it to be 'over the top'...and they got it. In my defense, an actors job is to give the client what they ask for. :) I must admit, we had lots of laughs along the way.
The intro to episode 9 counts as well since the creator of the intro, SegaSky, managed to get Jeff Lupetin, the voice of Gillian Seed from Snatcher, to voice it. Needless to say, slowbeef claimed to have listened to it ten times in the episode.
A fan managed to get the voice actor of King Graham to do the into to Episode 17.
"Hi! This is King Graham, and you're listening to Retsutalk! It may not be much, be it's sure beats the Town Theme. And I know I speak for everyone in Daventry when I say 'Cedric!' heh heh heh 'Fuck off!'"
PewDiePie posted an apology video at the end of the year, though to some, that seemed like a hollow gesture that was too little and too late. In response, slowbeef discussed the video.
Kuroinokaze gets one by making a longplay so inherently funny that slowbeef and Diabetus praised him for it.
The 2013 RetsuBlitz is worth mentioning here: in every day in February (except for the first), the guys uploaded, on average, about 3 videos per day - adding a total of 77 videos to their video count (it was 79, but unfortunately, at least two videos were removed; one is available on Blip and the other can be found in the comments section of the first Exmortis III video). The surge of videos had a number of interesting venues for the channel, including a few Wrongpuraes, several Retsufrashes, a Retsutalk podcast episode, and guest commentators from Facebook. Best of all, it was all set up to celebrate Retsupurae's 5th Anniversary.
Also: they actually Retsufrashed Meet 'N' Fuck Kingdom (albeit heavily censored). That's pretty awesome in and of itself.
Not only that, but they also Retsufrashed/Wrongpuraed the Grand Finale to the Exmortis series, which unlike the other Exmortis games, actually had to be bought to be played.
ezvidinc: If you are baked, Ezvid will automatically end your video at 4:20 minutes. As a safety precaution.
Jevandyr: I love how he has the FRAPS icon on his taskbar as if to show he couldn't get it working.
ezvidinc: Oh, that's Ezvid in "fake Fraps mode". Very popular user mode.
After the end of Ambition Part 8, PinstripeHourglass (the guy who played and recorded the game and paid ten god damn dollars in subscription fees for Slowbeef and Diabetus) decided to do a little bit of research on his own, and found the actual context of a quote that was used in that Ambition game. invoked
Slowbeef: Wow, who'd have thought that Michael Gibson didn't do good research on these games.
A Day in the Life of DarkSydePhil, another collab. Slowbeef notes in the description that he got over two hundred submissions. It helps that Phil has a pretty massive Hatedom.
In Retsutalk Episode 37, the guys got Ben Croshaw to guest on the podcast.
At one point, they do a riff on Deceased Crab who is known for being repetitive to the point of having most of their videos very very similar in terms of commentary. Near the end, it's revealed that they were never watching a video in the first place, and planned on sticking their commentary on top of a random one of his videos to prove their point.
