The ACLU has a funny/scary little Flash animation going on here.
The most disturbing thing about this to me is that it's not at all far-fetched. A bit alarmist, perhaps, but when I call the pizza place here, they know more about my pizza eating habits and history than I do. What's even more scary than that is that I like it. I just say, "What was that one I had 3 weeks ago? That was good. I want that one again." Then they take the money out of my checking account and send some guy (or a girl, once) to my house.
I like pizza.
