The first “actual” computer bug was found on September 9, 1947

On September 9, 1947, a team of computer scientists and engineers operating Harward University’s Mark II electromechanical computer started getting an error. They traced the error and found a moth trapped in a relay. The moth was carefully removed and taped to the logbook with a note saying “first actual case of bug being found”. Urban legend says this was the first case of a computer bug, but it’s not true.

Crocodile bigger than Lolong? [1823 Philippines Crocodile]

According to biology professor Alvin Silverstein’s 1980 book Nature’s Champions, in 1883, a giant saltwater crocodile bigger than Lolong was killed in the Philippines. It measured 27 feet (8.23 meters) from the tips of its snout to the end of its tail. It was also more than 2 tons in weight. Sources say it required the help of 40 men to bring its body ashore. And, when the massive crocodile was opened up for examination, individuals were taken aback to find the segmented remains of a horse, carved into seven distinct pieces.

There’s no photo of the crocodile, because of the record’s date, but if that story is true, it was the largest crocodile ever recorded.
