You’ve probably come across Will Flanary, aka Dr. Glaucomflecken, the internet’s most famous physician/comedian. For more than four years, the ophthalmologist has been gently roasting medicine by playing a rotating cast of characters — the emergency physician clad in cyclist gear, the “ortho bro,” the pediatrician in a unicorn headband. But he's also used his comedy to skewer the business of health care, including the confounding bureaucracies of insurance — with a special emphasis on UnitedHealthcare. First Opinion editor Torie Bosch spoke with Flanary about punching up in comedy and the reaction to the shooting of UnitedHealthcare CEO Brian Thompson.
