CBS4Denver did a "teaser" for a story coming up in the 10 PM news that cracked me up. It seems that millions of boxes of breakfast cereal have been recalled because of "a foul odor that's making some people sick." The story, they promised, would tell us "how to tell if your cereal has been recalled."
I just saw the story, and it said to "look for the letters KN before the 'Use before' date."
In case the foul odor isn't enough of a clue.
