A Nelson trailbike rider has become an internet sensation after posting a video showing him being attacked by an angry ram.
Marty Todd's YouTube video, in which the surly ram known as Rambro prevents him from riding up a dirt track, has gone viral after being featured on CNN and Britain's Daily Mail website.
"I was riding my trailbike up a hill when I came across this grumpy old ram with huge horns," Mr Todd said. "It charged my bike then started attacking me, [he's a] surprisingly powerful animal."
Mr Todd said he couldn't turn his trailbike around as he was on a steep hill and if he did the ram would have charged him side-on, which could have broken his leg.
He let him loose on his large scrub and pine plantation a few years ago with his "missus and a son" and didn't come across him very often.
"But when he appears, I'm always on guard," Mr Todd said.
While Rambro was a bit of a menace, he was also a "character and he is better than any guard dog".
