A woman sued the Cap'n Crunch people because her cereal didn't contain any "crunchberries":
On May 21, a judge of the U.S. District Court for the Eastern District of California dismissed a complaint filed by a woman who said she had purchased "Cap'n Crunch with Crunchberries" because she believed "crunchberries" were real fruit. The plaintiff, Janine Sugawara, alleged that she had only recently learned to her dismay that said "berries" were in fact simply brightly-colored cereal balls, and that although the product did contain some strawberry fruit concentrate, it was not otherwise redeemed by fruit. She sued, on behalf of herself and all similarly situated consumers who also apparently believed that there are fields somewhere in our land thronged by crunchberry bushes.
