Stumbling for Words

I accidently recorded CNN (yup, the DVR is full again) and I zoomed by and saw that there was an explosion of some sort in Dallas. The funny part was that after the anchor said, "There has been an explosion near the I-35" He had to fill up a huge amount of time and I expected him to start telling us a story about the light pole or something. Besides, all the traffic that was diverted what much else can you say?
