Male called saying "HI I'm from CBS news with Katie Couric and we need to know..." or something along those lines. "And we need to know how many people are in your household and if they're 18 or older, male or female." He also asked if he had the right number, and repeated our phone number. He avoided answering my questions about "Why do you need to know" and finally mentioned the survey at which point I said "hold on" and hung up.
