PISCATAWAY, NJ—A CNN report on a suicide bombing in Tel Aviv put Piscataway resident Larry Zahn in the mood for a falafel sandwich Monday. "Oh, man, I could go for some falafel right about now," said Zahn, 41, watching footage of injured Israelis being loaded onto ambulances. "A big pita stuffed with falafel, hummus, lettuce, and lots of tahini sauce. And some dolmades on the side. Yeah." In January 2001, a CNN report on an Indian earthquake that killed 2,000 gave Zahn an intense craving for chicken biryani.
