I've never seen one.
As to how it's done, i watched an interview, and apparently it takes practice. And it could have something to do with peristaltic movement. Or a combination.
I, myself, participated in a pie eating contest at our local county fair. . . but it was banana cream pie so no big thing. I didn't win. . . but I was a pie eating mess.
If there was anyone here I would nominate to participate in an eating competition, it would be UK.
The first time I met him was at dinner with Vickie and Les when UK was in town for a game. He had a cheeseburger. . . mind you, not a White Castle type. . . we blinked. . .turned. . . and it was gone.
Thus, he'll forever be known for his two second cheeseburger.
