Despite the many misunderstandings, Beckham, Cameron and Prince William are all desperate to bring the nation's favourite sport home.
We (probably fortunately) failed to find any photos of the real Cameron looking like this, but these two of Dugald Bruce-Lockhart definitely made us laugh...
The Three Lions runs at the Pleasance Beyond until 26 August 2013.
