Terry, the British sheep with an upside down head is becoming an internet sensation.



But is it real?



The owner of Terry's YouTube video, which already has more than 65,000 views in five days, says it is.



Allan McNamara found the sheep at his friends' farm, and said it was born with his head the wrong way around.



"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 sheep can," he said on YouTube.



McNamara wouldn't disclose the whereabouts of the farm, only saying it was in England.



He told the Daily Mail they had to give the sheep a name, so picked Terry.



"Its spine is curved as far as I can tell. I don't think it's in any pain - it certainly seemed as normal and docile as sheep normally are. It's crazy," he said.
