TV historian Dan Snow mocked himself in a hilarious online video after he was the subject of an Alan Partridge joke about nepotism.

Last night's episode of This Time with Alan Partridge featured a character named Sam Chatwin, a historian and parody of Snow, who was promoting his new TV series War Machines.

During the interview, Steve Googan's alter-ego pondered how Chatwin had landed the job of presenting such a high-profile history series, saying: 'Little-known fact: your father was head of factual programming until recently, wasn’t he?'

Responding to the light-hearted jibe, Snow created an online video featuring his own historian father Peter Snow, 80.

The clip shows Dan insisting he is 'the real deal' before he reels off a string of history facts, which it later emerges are being fed to him through an earpiece by his father.

The video was praised by Twitter followers and fellow historians alike, with many hailing the father and son's excellent sense of humour.

The clip opens with Dan standing at the site of the Battle of Culloden saying: 'Now some mean people have been saying I’m not the real deal. I don’t know anything about history and I’m only here because of my dad.

'To you I say, "How can this be true?" I’ve even got my own podcast. I’m standing here - look my dad’s not here. I’m standing on the battlefield of Culloden in Scotland - the last battle on British soil in 1746. I know loads about history I know other things too.'

The clip ends with Scottish historian Neil Oliver, pictured, lowering the book he's reading and telling the camera: 'What a pair of t***s'

Dan then puts his finger to his ear before adding: "I know that the Spanish Armada was defeated in 1588. I know the battle of...'

The video then cuts to his father, Peter Snow, who is holding a microphone and wearing headphones, saying: 'The battle of Waterloo 1815.'

The shot returns to Dan who repeats the line, saying: 'The battle of...yes, the battle of Waterloo was in 1815.'

After being prompted to mention Hastings and 1066, Peter gets his son to say the First World War was sparked by the assassination of Archduke Franz Ferdinand.

A very confused Dan says 'artichoke' before plaintively uttering: 'Dad?'

It prompts Peter to remove his headphones and say: 'Useless.'

Twitter users love Dan and Peter Snow's video which show the father feeding lines on key historical battles

Dr Janina Ramirez, an Oxford academic, was among those who responded, posting: 'A-MA-ZING'.

Another said: 'Oh that’s funny.....hahaha! Love the addition of Neil Oliver at the end...genius.'

A third wrote: 'So WW1 was fought over artichokes,' while another posted: 'Hilarious! Well done men!'
