What is tupperware used for?

Tupperware, is one of the greatest inventions in American History. Tupperware is so important because whenever we, Americans, of this generation, need our food to be hot, and stay hot, Tupperware is our Hero. Whenever we need to store food, our source of fuel, we get out a Tupperware container from our lovely kitchen cabinets, and what do we do next? We conveniently store it in a wonderful Tupperware container!
