Who knew that sheep actually screamed?! Well, thanks to this viral video, now more than 12 million people know this rather unusual fact.
This screaming sheep is so famous that it has now appeared on a number of television shows, including Russell Howard's Good News on the BBC, as well as E4's Rude Tube.
The sound of the screaming is also played from time to time on Radio 1's afternoon show, with the delightful Scott Mills and Chris Stark. There's even a nighttime version of this film, which is a bit weird, with the nocturnal noises appearing rather like a cross between aliens and angry birds.
