In this lively Season 2 finale of Rabbit Hole of Research, hosts Joe, Nick, and Georgia are joined by returning guest Mary Schons and Christmasist Kathryn “Kat” Sterbenc to do two things at once: look back at a season spent separating science from handwavium, and finally tackle the perennial holiday argument, Is Die Hard a Christmas movie?
Over the course of Season 2, the show explored science through the lens of fiction, asking how fast is too fast, what happens when time misbehaves, and what it looks like when ecosystems, societies, and technologies buckle under pressure. From noir to kaiju, superheroes to slashers, stretched bodies to stressed systems, every episode dug into the real science beneath the stories we love.
As the season closes, that same lens turns toward Christmas movies, stories that look comforting on the surface, but are almost always about pressure: people forced together, deadlines that can’t move, and systems pushed to their limits right when everything is supposed to feel magical.
The conversation starts with the crew sampling the worlds second strongest beer (Snake Venom) and swings widely, from It’s a Wonderful Life and Home Alone to Trading Places, The Thing, and of course Die Hard, as Kat lays out her criteria for what makes a “true” Christmas movie and Mary pushes back with thoughtful counterarguments. Along the way, the group explores holiday mythology, redemption arcs, cultural tradition, and even the science behind Frosty the Snowman and Jack Frost.
Part season recap, part holiday debate, and part festive rabbit hole, this episode unwraps what makes stories endure. Whether they’re built to rewatch every December or just held together by a little Christmas Handwavium.
Stay Safe, Stay Curious, and Merry Christmas you Filthy Animals!

Joe:
Red Line: Chicago Horror Stories Anthology featuring a new story by Joe!
Joe’s Sci-fi physiological thriller Novel: Will You Still Love Me If I Become Someone Else?
Essay by Joe: From Beyond Press: Specific Knowledge: Jotham Austin, II, PhD on Transformations in Fiction
Joe explores how many calories it would take to transform into monsters across sci-fi and horror—think 222 Big Macs and tubs of Cherry Garcia.

Fun Ideas and Facts from the Episode
Christmas movies are pressure-cooker stories.
Nearly every film discussed—whether action, horror, or comedy—uses Christmas as a narrative deadline that forces characters, systems, and relationships to break or transform.
The Grinch’s heart “growing three sizes” would be a medical emergency.
That moment implies instant cardiac hypertrophy or cardiomyocyte hyperplasia—neither of which is survivable without extreme intervention.
Frosty the Snowman would need advanced nanotechnology.
Without bones, muscles, or vocal structures, Frosty’s mobility and speech only make sense if his hat contains nanomachines and AI continuously rebuilding him.
Home Alone is statistically lethal.
Referencing MythBusters-style analyses, the injuries sustained by the burglars would be fatal multiple times over—making it arguably more violent than Die Hard.
Freeze distillation—not brewing—makes the world’s strongest beers possible.
Snake Venom (67.5% ABV) isn’t fermented to that strength; instead, it’s freeze distilled, a process where water freezes before alcohol and is removed as ice, concentrating the ethanol. The result behaves more like a fortified spirit than a traditional beer, hence why it tastes closer to solvent than stout.
Episode Highlights
00:00 — Welcome to the Rabbit Hole of Research
Joe opens the season finale from the basement studio, setting the tone for a wintery recap and a holiday-themed descent into science, culture, and argument.

05:08 — The World’s Strongest Beers
The group revisits last season’s tradition by sampling Snake Venom, the world’s second strongest beer, and explains freeze distillation as a legitimate (and dangerous) way to concentrate alcohol.
06:37 — Debating Christmas Movies: Die Hard and More
The central question emerges early: what actually makes a Christmas movie, and does Die Hard qualify, or is it just an action movie set in December?
