When the average person says they're going to stuff their face at a barbecue, they probably end up eating a max of five hot dogs. When competitive eater Joey Chestnut stuff his face with hot dogs, he can consume up to 69.

You may be wondering how this is possible, and thankfully (depending on your gag reflex) ESPN's John Brenkus did a special Sports Science feature on what all of that food looks like inside a human stomach. Warning...maybe don't watch this while eating.

Duly noted - don't invite Joey Chestnut to your next barbecue. Unless you want to be staring at him like this the whole time as he goes up for another serving.
