The third what now?

Tonight on the news there was a woman from San Francisco, or at least California, who said that a while back (before 9/11) there was a FEMA drill or simulation that dealt with three scenarios: a terrorist attack on NYC, a hurricane in NO, and an earthquake in SF, and what with the first two having come to pass, she was "waiting for the third shoe to drop." It's clear what she means, of course, but that struck me funny.

Oh, and there's a new Philosophers' Carnival.
