This week on Flightless Bird, David sets out to make sense of the very confusing American healthcare system. Joined by Monica, he tries to figure out why some Americans end up paying their own ambulance bill and why over half of the American population is riddled with medical debt. David talks to Luke O’Neil - the journalist and writer behind the popular newsletter "Welcome to Hellworld" - about why it falls on children to raise money for their parent's medical bills and discovers why in the US healthcare system teeth are considered “luxury bones”.

This week on Flightless Bird, David sets out to understand what makes the American diner experience so special, by traveling to Reno, Nevada. There he meets the staff of Peg's Glorified Ham N Eggs and meets the regulars who've made the diner their home away from home - including Rainbow Man, a man obsessed with painting human bodies at Burning Man. What makes a diner a diner? How have they changed over the years? David and Monica discuss their various diner experiences, from fights to excessive milkshake consumption.

This week on Flightless Bird, David sets out to discover why America loves circumcision so much, to the point where 115 million American men now find themselves without a foreskin. Joined by Monica, he tries to figure out why this medical procedure became so popular here, leading to some medical diagrams not bothering to include a foreskin anymore. David talks to a man in his 30s who’s furious he got circumcised when he was a baby, and another who’s annoyed he wasn’t circumcised, as he considers getting an adult circumcision. David talks to a doctor who’s carried out hundreds of circumcisions to find out what all the fuss is about, and spends time with Georganne Chapin, Executive Director of Intact America - who wants circumcision to be thrown out the window.

This week on Flightless Bird, David sets out to understand a game that simply doesn’t exist in New Zealand: American Football. He tries to figure out America’s most popular sport and asks why over 100 million Americans watched the Super Bowl. After watching the Super Bowl for the first time, David travels to Seattle to get schooled by NFL Hall-of-Famer Walter Jones, who was drafted by the Seahawks in 1997. He discovers what a locker room smells like and why some football players love to chew gum so much. Walter also opens up about his theories on the existence of extraterrestrial life.

This week on Flightless Bird, David sets out to understand America’s obsession with bottled water. Joined by Monica, he tries to figure out why tap water just won’t cut it in many US States, leading Americans to spend billions on bottled water every year. David talks to author and scientist Peter Gleick about tap water myths, and how some bottled water companies have accidentally added things like arsenic and cricket parts to their bottled creations. We discover why a new sports stadium purposefully didn’t install enough public water fountains and get to the bottom of whether carcinogenic chemicals leech from plastic bottles creating a deathtrap.
