The NY Times has a short documentary film by Errol Morris on El Wingador, a five-time winner of the Wing Bowl. My favorite line from the film, uttered by an off-camera Morris:
Wait a second. That's cannibalism!
Though his several wins came early on in the competition's history, El Wingador is still competing in the Wing Bowl. In the 2012 competition, held today, El Wingador came in third while Takeru Kobayashi completely demolished the competition in his first attempt, eating 337 wings in the process.
