It was pretty wild. We always figured it fed 10-15 when people asked. We had a challenge for 2 people to eat the whole thing in an hour. The real issue was that the competition pizza had to have 9 toppings. That thing had to be about 15 pounds. It was 60oz in just dough. No team got really even that close (MAYBE 2/3 before quitting was the best performance).

I could do it with someone. I ate 5 of pizza huts largest pizzas and 4 breadsticks bc someone thought it was impossible. Toppings are mushrooms, onions, green peppers, black olives, green olives, chicken cubes, sausage, pepparoni, and jalapenos. Oh and some milk. Cant eat that much pizza without milk.

Also each slice of the pizza hut pizza was dunked in milk for 4 seconds then eaten in 2 bites. Ill add that I did throw up 3 pizzas worth and all the breadsticks afterwards, and pretty much a whole gallon of milk. I was about 6 inches larger in the belly after that....
