Spare ribs are for people who don't want actual ribs. I can easily put down a slab of backs, easily. I have also eaten a large pan super supreme minus olives from Pizza Hut. Twice actually. Haven't done the Doritos but I know I can. This is a shame but just last week I ate 3/4 of a bag with the tostitos nacho cheese dip. I only stopped because I ran out of dip.
My most impressive food feat was in high school where I had 10 tacos from taco tico for lunch and ran 4 miles at cross country practice three hours later with no issues. Another time in high school after cross country practice I had 3 full sized snickers bars, an entire bag of lays sour cream and onion, the size smaller than family size, and a two liter of lipton lemon tea. I then an hour later went to the gym to shoot around to get ready for basketball season; none of that crap stayed down.
