Jack wants to be Mad. In every meaning of the word, Mad.
Jack wants to go Mad every time he eats, beyond mere human portions. Jack wants to be Mad about the quality of the food and service, Jack wants to be Mad about the prices and the people. Jack wants to be Mad about the latest inconvenience, but Jack would also be Mad if he had nothing to be Mad about, complaining that its too quiet and the other shoes about to drop. If Jack had access to the Big Red Button, he'd go MAD on everyone he thinks has ever wronged him.
