Jon Stewart of The Daily Show: Fat cats and Crumbums

Fat cat is slang term which describes a rich, greedy person who, due to ownership of large amounts of capital, is able to "live easy" off the work of others. Often, those labeled "fat cats" will reap a sustantial financial gain from a business, while the business itself, and the people who are employed by it, do not. The term is also sometimes used to refer disparagingly to wealthy contributors to a political campaign. The term stems off from the fact that since rich people can buy a lot of food, they both tend to resemble each other, the owner and the cat, in girth of waist, haughtiness, and a holier-than-thou attitude.
