Peter and Aubrey work through a list of fitness and health myths — everything from whether your pee needs to be clear to whether cold plunges do anything besides make you cold. Peter, a physician who actually researched every item beforehand, delivers verdicts with increasing exasperation at the wellness-industrial complex. The episode gets off to a chaotic start when Aubrey's city issues a tornado warning mid-recording, which they handle with an extremely relaxed amount of concern.

SHOW NOTES

• Unplanned cold open: A tornado warning interrupts the recording right before Aubrey introduces the topic — complete with sirens, an emergency alert, and Peter calmly browsing tornadohq.com while Aubrey checks whether the sky is green.
• The episode's framing: Aubrey compiled a list of fitness myths she wanted Peter to address; Peter researched each one before recording to make sure his gut answers were correct. (They were.) The through-line is the firehose of fitness misinformation on social media versus the relative rigor of older media.
• Hydration myths — two myths addressed: No, you don't need to hit a specific daily ounce target (it varies wildly by body size, activity, and weather); and no, your urine does not need to be clear — pale yellow is the actual target. Peter notes that clear urine can actually indicate overhydration.
• Caffeine and dehydration: Totally debunked. Caffeine is a very weak diuretic, and you'd need 500–600mg to see any meaningful effect — well above a normal cup of coffee or tea.
• The 10,000 steps myth: The number came from a 1965 Japanese pedometer called the Manpo-kei ("10,000 steps meter") — a marketing name, not a medical recommendation. Research suggests meaningful health benefits plateau around 6,000–8,000 steps, and the biggest gains come from going from ~2,000 to ~5,000.
• "Breakfast is the most important meal of the day": A cereal company marketing line from the 1980s, not medical advice. Peter's verdict: if you like breakfast, eat it; if you don't, don't. There's no metabolic magic to eating first thing.
• Electrolytes for regular exercisers: Save your money. Electrolyte replenishment only becomes relevant after roughly four hours of continuous exercise. For everyone else, you're just making your urine more expensive.
• Zone 2 cardio and fat burn vs. fat loss: A nuanced one — Zone 2 does preferentially burn fat during exercise, but that doesn't translate to greater fat loss overall. What happens in the other ~10,000 minutes of the week matters far more than what happens during 150–300 minutes of cardio.
• Cold plunges: Peter is unimpressed. No meaningful physiological benefit for most people; may actually inhibit muscle protein synthesis after resistance training. Heat is better post-lift.
• Detoxes and cleanses: The one that makes Peter visibly angry. Your liver, kidneys, GI tract, and lungs already do this — it's literally their job. No juice cleanse replaces a failing organ, and anyone selling you one has something to profit from.
• Carbs, protein, and the "no eating after 6 pm" rule: All myths. Carbs are your brain and body's primary fuel source; processed carbs are the problem, not carbs generally. Protein needs are real but far lower than supplement companies suggest (~0.82g per pound of bodyweight). Meal timing within a 24-hour window doesn't affect fat storage.

Peter and Aubrey dig into Dungeon Crawler Carl by Matt Dinneman — all seven books, with book eight nine days out. They cover how they each came to the series, why the audiobooks (narrated by Jeff Hays) are basically the only correct way to experience it, and what separates DCC from the litRPG slop Peter burned out on years ago. The back half goes full spoilers: theories on the ending, whether Donut survives, and a frank debate about where DCC actually sits in the pantheon — fun and entertaining, they agree, but not literature, which is fine — and which leads Peter to take a brief shot at Brandon Sanderson on his way out the door.

SHOW NOTES

• How they found the series — Aubrey was skeptical (a talking cat named Princess Donut did not sell her), but Hayden's enthusiasm eventually won out; Peter needed something lighter after slogging through The Three-Body Problem book two.
• The audiobook question — Both agree Jeff Hays is essential; his voice work is so distinctive that he omits dialogue tags in places because you simply know who's talking. Audiobook sales reportedly outpace ebook and print combined.
• The litRPG problem — Peter contextualizes why he's wary of the genre: most of it trends toward male power fantasy with inexecrable harem dynamics. DCC's reluctant, morally grounded protagonist is a deliberate contrast.
• Matt Dinneman's origin story — Before the pandemic, he traveled the country doing commissioned cat portraits at cat shows. A staring Persian cat inspired Princess Donut. COVID shut that down; he started posting chapters on Royal Road, and it exploded from there.
• Series overview (spoiler-free) — Earth gets strip-mined by the Borant Corporation, collapsing all buildings and turning the planet into an 18-level dungeon broadcast as galactic entertainment. Carl and his now-sentient cat Princess Donut navigate it while inadvertently becoming agents of chaos against the whole system.
• SPOILER SECTION: Series theories — Both think Carl will dismantle the Borant Corporation rather than complete the dungeon; Peter predicts the series ends at level 12, with the deity/ascension mechanics being the key. Ten books total, per Matt Dinneman's own Reddit comments.
• Will Donut survive? — Neither is confident. Peter says if Donut dies, he stops reading; Aubrey thinks losing her would send Carl fully off the rails. The cover where Donut is absent did not help their anxiety.
• Favorite moments — Aubrey's top two: Carl telling Prepotente to "eat a bag of dicks," and Donut screaming "die motherfucker die" while drunk. The Prepotente/Carl reconciliation in book seven gets genuine appreciation from both.
• Jeff Hays fandom — He's locked into the Carl and Donut voices permanently; he's confirmed he can't use them for other projects. A convention clip of Hayes singing "Wonderwall" in the Donut voice while Matt Dinneman plays guitar on stage is, per Aubrey, simply iconic.
• The verdict — Fun books, not great books, and that's okay. Peter lands a parting shot: Brandon Sanderson could learn something from DCC about not taking himself quite so seriously.

Peter and Aubrey work through all 37 official MCU films on Peter's custom tier list tool, placing each from S down to D with no shortage of strong opinions along the way. The results are roughly what you'd expect from two Marvel fans who still remember opening-night midnight showings — Thor: Ragnarok and The Winter Soldier are untouchable, Eternals and Iron Man 2 are not. The episode also touches on the MCU's recent creative upswing (Thunderbolts, Fantastic Four), the ongoing wound that is Secret Invasion, and a pre-show check-in that includes Aubrey's genuinely harrowing week of tornado evacuations in Madison.

SHOW NOTES

• Check-in: Peter escaped a work trip in Austin early by paying $75 for a same-day flight change — no business casual required, shorts were involved. Aubrey's week involved actual tornado warnings in Madison, a mid-workday shelter evacuation with her kids, and baseball-sized hail; she later raced home with Hayden to beat a second tornado approaching from the west. Friday brought a school district preemptive cancellation and, fortuitously, weather pay.
• Episode setup: With Avengers: Doomsday trailer apparently shown at CinemaCon (not yet public), Peter thought it was a good time to tier-rank all 37 MCU movies using his custom tier list tool. He and Eden did a bracket format on The Middle of Culture previously, but Peter prefers the tier list because it doesn't force unfair head-to-head matchups.
• S tier (locked in): Thor: Ragnarok, Avengers: Infinity War, Captain America: The Winter Soldier, and Spider-Man: No Way Home. Peter notes The Winter Soldier is probably the best MCU film, even if not his personal favorite; No Way Home earns its S on pure emotional impact, despite Homecoming arguably being the tighter movie. Both agree Infinity War is the stronger film over Endgame.
• A tier highlights: Black Panther, Black Widow (Aubrey advocates for it; Peter concedes despite CGI complaints), the original Avengers, Civil War, Endgame, Thunderbolts, Fantastic Four: First Steps, Guardians Vol. 1, Homecoming, Ant-Man, and Iron Man 1. Peter is bullish on both Thunderbolts ("hits emotionally a lot harder" than Fantastic Four) and Fantastic Four ("it's got the juice").
• B tier: Guardians Vol. 3, Wakanda Forever, Spider-Man: Far From Home, original Thor, Guardians Vol. 2 (Peter's least favorite of the trilogy, despite online discourse claiming otherwise), Deadpool & Wolverine, Captain America: The First Avenger, Doctor Strange, and Shang-Chi — though Peter notes Shang-Chi gets docked for Marvel's failure to do anything with the character afterward: "My boy Shang-Chi deserves better."
• C and D tiers: Age of Ultron lands in C; Iron Man 2 in D ("you can't enjoy the experience of Iron Man 2 ever again"). Eternals earns a D with Peter suggesting he might genuinely prefer Iron Man 2 over a rewatch. Brave New World lands in D simply because neither of them has had any interest in watching it — the tier list as disinterest metric.
• MCU fatigue and cautious optimism: Post-tier-list conversation touches on the post-Endgame drop-off in quality and excitement. Aubrey recalls having a nightmare the night before the Endgame midnight premiere that they couldn't go see it — that's the level of hype she wants back. Both see Thunderbolts and Fantastic Four as signs of an upswing heading into Doomsday.
• Secret Invasion tangent: Peter revisits his custom-built tier list feature (a bonus below-D tier for truly irredeemable content) — originally created for DC's Black Adam, but Secret Invasion is the MCU equivalent. Six episodes and rage-quit; he says it soured him on MCU TV generally, leaving him behind on Loki S2, What If S2, Echo, and Daredevil Born Again.
• Tease for next episode: Aubrey mentions she already has an outfit planned to go with next week's topic.
