NBC Nightly News anchor Brian Williams was forced to address the nation yesterday with the addition of a faulty fire alarm, which blared loudly in the background for nearly two-thirds of the broadcast. Even though Williams remained largely unfazed by the disturbance, the incident served as fodder for Jon Stewart on tonight's Daily Show—that is, until his own segment was interrupted by a loud siren. (I suggest it was Brian Williams, in the kitchen, with the bullhorn.)
