This guy has eaten nothing but mac and cheese for years. I am surprised his body hasn't broken down yet.
The worst part of the whole thing though is just the laziness of the guy.
Like if you are going to eat one food only you may as well go all out and make it top tier. Like hand make your own organic top notch pasta and add gourmet European cheeses to it. But no he chooses to only eat pre-packaged mac and cheese like a redneck.
