BBC reporter James Landale was just looking for anonymous losers to share their thoughts on the proposed Heathrow Airport expansion when he ran into none other than the Fonz, a.k.a.

Landale could barely maintain his composure, and critics expect this to be remembered as the moment when BBC’s “man on the street” interviews jumped the shark.
