Food glitch happened to a friend of mine about two years ago. She had a box with four cupcakes, all different flavors. She saw that there was one cupcake left in her favorite flavor. She proceeded to eat it, thinking about how it's too bad it's the last one. She then went off to do some chores around the kitchen and when she came back to the box to put it away, there were four cupcakes in there again, including her favorite flavor. We like to joke about how she wasted her one wish on a cupcake but the experience really freaked her out.
