How the wedding mystery became a podcast

Zach sits down with Karen Whitehouse and Helen McLaughlin, the married duo behind the cult-hit podcast Who Shat on the Floor at My Wedding? https://www.whoshatontheflooratmywedding.com/

What began as a deeply confusing—and slightly sinister—incident on their wedding boat (“the matrimonial turd,” as Karen lovingly calls it) became a three-year dinner-party story that neither of them could stop telling. Their friends couldn’t stop talking about it either. Eventually, with Helen’s wholehearted encouragement (and financial backing), the couple turned their whodunnit into a comedy podcast—one that later went viral, beat Joe Rogan for a week, and now brings joy to listeners around the world.

Karen and Helen share how the project grew from a joke into a mission: spreading joy, escapism, and silliness during some of the hardest seasons of their lives. They talk candidly about infertility, grief, bad therapy, moving from Amsterdam to a tiny English village, and the emotional evolution that shifted them from distraction to genuine self-work. Their chemistry is undeniable: they tease each other, interrupt each other, apologize quickly, and know exactly how to hold space when things get tough.

Together, they explore how detective work mirrors relationship work—don’t make assumptions, stay curious, pause your biases—and how “learning each other’s love languages” helped them survive both big heartbreak and small bickers. It’s a conversation full of heart, humor, British slang, and surprisingly profound insights about partnership.

Key Takeaways

• Comedy and curiosity can transmute pain – Turning their wedding mystery into a podcast helped them process, connect, and bring comfort to listeners going through dark times.

• Don’t make assumptions – Their detective work taught them that bias blinds you… in crime-solving and in conflict with your partner.

• Joy is a choice – Both see “spreading joy” as part of their life purpose, especially after Helen’s grief and Karen’s infertility journey.

• Learn each other’s triggers – Helen’s fear of abandonment and Karen’s need for praise once clashed; learning their love languages changed everything.

• Apology is a superpower – A small bicker resolved quickly after Karen simply said: “I have to apologize.”

• Big life transitions shift emotional bandwidth – Moving from Amsterdam’s buzz to the English countryside forced them to slow down and actually feel their feelings.

• Avoid two bottles of white wine – Their worst arguments were fueled by it. (“Anything else is fine!”)

• Support > solutions – During IVF heartbreak, grief, and major transitions, what mattered most was showing up for each other with compassion.
