KANKAKEE, ILLocal citizens are abuzz with the news that a local Angus beef hamburger will be featured in a national Weber gas-grill TV commercial that begins airing Monday. 'We are all just so proud,' Kankakee Mayor Donald Green said of the burger, which appears seated on a seeded bun and dressed with ketchup, pickles, lettuce, and a slice of tomato. 'We've had some great sandwiches in this town, but none have gotten this kind of recognition. All of us who knew the burger had a hunch it was going to go on to great things.' According to Green, the burger's talent agent is currently negotiating details for the burger's inclusion in a diner scene in an upcoming Will Ferrell movie.
