There was a "being silly" package for error messages, I believe, but I can't recall where exactly. While software usually offers a debug feature, I really like the idea that software also can have a silly mode, or similar, like Easter eggs which are triggered by a specific date. It takes away the seriousness of using a computer and lightens up the mood. Also good for motivation and morale.
