The producer got a couple whose house was being undermined by the fire to stand close to a smoking hole in the ground.
Kopel finishes the interview by telling the couple to get away from the smoke because it's not safe.
The couple was re-interviewed complaining that Kopel made them look like idiots for standing near the smoke, when that's what the producer wanted them to do.
Started by the local government saying it was OK to light the local dump on fire IIRC. Still burning to this day.
