Catch a ride upon a moonbeam and try this one on for size. Scientists in North Korea are claiming that unicorns actually existed. The report, released by the Korean Central News Agency (KCNA), “reconfirmed” the burial site of a royal unicorn allegedly ridden by King Dongmyeong of the ancient Korean kingdom of Goguryeo. Scientists say the proof lies not in something silly like, say, evidence of a horn on a horse, but in the rectangular rock engraved at the entrance of the grave, which reads “‘Unicorn Lair.” Full disclosure: KCNA isn’t exactly known for accuracy. The news agency once reported that deceased leader Kim Jong-il had not only “invented the hamburger” but written “1,500 books.” Next up, Santa Claus?
