In a mock error Xbox One users have been getting recently an interesting reference to pony has been appearing! Apparently the error was part of a test string that was never meant to display but for some reason now has so if it pops up on your Xbox, don't be concerned, just smile at the nod some Microsoft programmers made to pony.
Thanks to FlyingSixtySix, Bronyfazz and Bryan for first sending it in! Get a screenshot of the error after the break.
