Though it may not go as viral as Fenton's dogged (geddit?) pursuit of an alarmed herd of deer, this clip of a golden retriever starting on a kangaroo (?!) in the Kent countryside is almost as good, mostly down to the dog's owner bellowing "LEAVE IT!" as the retriever takes off, as if she's separating two drunks outside a club.
"Leave it mate, he's a dickhead, he's not worth it. Come back inside, I'll buy you a drink."
Also, if anybody could confirm just why there is a kangaroo in Kent I'd be extremely grateful.
