The answers—and more questions—in the latest TV ratings quiz:
1. Name three big shows that look even bigger than they did last fall. NCIS rose to No. 1 in the latest Nielsen rankings. House returned to the Top 10. The Big Bang Theory broke into the Top 20.
2. Name three big shows that don't. The Mentalist, CSI: Miami and Desperate Housewives all fell out of the Top 10. CSI suffered the most viewer defections from fall premiere to fall premiere, but still wound up at No. 7 for the week.
3. Can Dollhouse get any smaller? Than last season? Yup. Joss Whedon's show averaged only 2.5 million diehards for its latest opener, bad for 110th place.
