Whats scary is that the bread itself accounts for 1/4 of the calories, most of which are from the dreaded carbohydrate.
Athletes often have to eat 6-8,000 calories a day, but for a normal person that would be at least 3 complete days worth of food, if not more.
Also, props to comparing to a Gamecube. Had he used an X Box the sandwhich would have been dwarfed in size.
