Following the boneheaded Bullingdon Club behaviour of Cameron, Osborne and Johnson, there are two ways for a comedian to deal with having attended Eton and Oxford; to ignore it and adopt a mockney accent or milk it for all its worth.

Twenty-four-year-old posh lad Ivo Graham goes for the latter. And to jolly good effect too.

Having admitted he used to only briefly refer to his education as a "boy's boarding school", now he uses ‎it as the crux of his act, not least because it helps him explain why it took him so long to lose his virginity.

There was a touch of the Simon Amstell‎ about him as he painstakingly recounted his "arid" years, all seemingly stemming from his mother's warning that he would not be respected if he slept with someone in freshers’ week: "I basked in that respect for the next four years," he confessed.

Graham is at his best when playing on the juxtaposition‎ between a background full of opportunity and his social ineptitude.

The fact that he now has a girlfriend could have scuppered this, but self-deprecating lines such as: "When I call and ask to sleep in her bed, three times out five she will agree," ensured he was still seen as the likeable outsider, whatever his background.
