I don't think I've ever seen a story like this before, but in New Zealand, a baker got fed up with a particular customer who was ordering a secondary cake for her sister's engagement party. The baker, Emma McDonald, says she was give no instruction other than that the cake be chocolate.

She fashioned a chocolate cake in the shape of, well, feces. She wrapped it up and delivered it to the engagement party where it was unwrapped and greeted with mixed reaction.
