His accents posher though and I'm yet to hear him say ''monging it''! Plus his family have been scrapping a lot longer, stolen from Wikipedia:
Blunt was born at a military hospital in Tidworth, Wiltshire, England, the first child born to Jane and Charles Blount. Blunt spent his early childhood living in England, Cyprus, and Germany, where his father, a Colonel in the British Army Air Corps, and military helicopter pilot, was posted at various times. He has two younger siblings. His father instilled in his son a love of flying, and Blunt earned his pilot's license at age 16. The Blount family has a long history of military service, dating to the 10th century.
Poshest bloke to go on ops is an anaesthetist with his own title who's relative was at Welllesly's side. Mad as a hatter though, but really posh. Got caught by his mum fishing in their river when i was a teenager. She took £10 of me cash in hand for "permission". Tackled her about it at a social do gave me the cash back and said I was banned for life (not).
