Sheep 'born with upside down head' - video
Video footage of the animal has been posted on YouTube showing the apparent quirk.
The sheep, named Terry, is said to be leading a perfectly normal life on a farm somewhere in Britain.
A friend of the farmer who owns the land that Terry has been grazing on filmed the footage.
The friend, who goes by the name of Mr Macca, has already racked up nearly 50,000 views with the video.
Macca writes: "He lives happily and has been checked by a vet to ensure he is in no pain.
"He can eat, sleep and do everything other sheeps (sic) can."
