It was British Prime Minister Winston Churchill who inaugurated Britain and America's "special relationship," coining the phrase in a 1946 speech. And while Prime Minister David Cameron and President Barack Obama may not have had the political intimacy and ideological alignment of Ronald Reagan and Margaret Thatcher, and indeed have had their rough patches, they nonetheless have shared a unique and jocular special relationship all their own.

"Yes, he sometimes calls me 'bro,'" Cameron once conceded of Obama.

With Cameron retiring, here's a look back at this particular special relationship, built, it seems, on the pillars of food and sports.
