A pony perplexing German commuters on the subway has become the latest internet sensation.
A YouTube video of the brown Shetland pony's antics on Berlin's S-Bahn - an overground subway similar to London's Tube - has been watched nearly a quarter of a million times since it was posted on Thursday.
A mystery blonde woman, in her twenties, can be seen nonchalantly leading her horse on to the train.

She held the horse on a short leash as it stood patiently surveying other passengers.
Fellow commuters were bemused by the bizarre scene - but quick to photograph and film the cute pony.
Passenger Jarkko Riihimaki said: 'This was supposed to be a normal trip home with the S-Bahn.
'After one stop, a girl - pretty conventional looking - comes in with a pony. Yes, with a pony!
'I don't know what to say about the whole thing.'
A S-Bahn spokesman failed to see the funny side of the incident, saying the horsey passenger clearly violated its travel policy.
Spokesman Burkhard Ahlert said: 'One may smile but according to our transport regulations, this is clearly not allowed.
'This clearly violates our conditions of carriage.
'A horse can be dangerous. What if it escapes? The S-Bahn is no place for such animals.
'We have informed the police already.'
He said that it is believed that the pony belongs to a circus troupe that collects donations.
