A Utah man got a little testy when passengers in a neighboring car, re-enacting a famous TV spot, gestured for him to roll down his window and asked if he had any Grey Poupon mustard. "Here's your Grey Poupon, roll your [expletive] windows up," said the 22-year-old, who grabbed a handgun and pointed it at them. One of the three got his license plate, and police later charged him with aggravated assault, the Salt Lake Tribune reports. (More mustard stories.)
