have you ever heard of error 418 I'm a little teapot? It was coded in case we ever have computer powered teapots and computer powered coffee pots. This error would be if we tried to make coffee with a tea pot, to remind us that the teapot is truly a tea pot and not a coffee pot. It was originally made as a programmer's April Fool's joke a couple years ago, but it's actually looking like it will become needed in everyday life. Error 418 is truly a one-of-a-kind error.
