Found a bug? Report it

You've found an easter egg!

On September 9, 1947, engineers working on the Harvard Mark II computer found that it was malfunctioning because a moth had gotten stuck in a relay. They removed the moth and taped it into the logbook, calling it the "first actual case of a bug being found." This is widely regarded as the origin of the term "debugging" in programming, though the term was used humorously at the time. The logbook with the moth is now preserved at the Smithsonian National Museum of American History.
