Asking a fellow driver if they have any Grey Poupon is...

While sitting at a red light in Salt Lake City, Vitaly Kovtun had another driver pull up beside him, roll down the window and -- in reference to the famous mustard commercials -- ask, "Excuse me sir, do you have any Grey Poupon?" The 22-year-old was not amused, reaching into his glove compartment to pull out a gun. Pointing it at the other driver, Kovtun said, "Here's your Grey Poupon, roll your f---ing windows up."

Kovtin has since been arrested for felony aggravated assault.
