We're big fans of John Oliver here is Balls Towers but I have to admit, he's let the side down with this performance on David Letterman.
Letterman clearly doesn't get the idea of English soccer and so asked Oliver to explain the concept of the football league system to him. After Oliver's quick lesson, Letterman now probably thinks there are 19 teams in the Premier League, and if the likes of Mansfield Town get 90 points in League Two and Man United get 87 points in the Premier League, then Mansfield would replace United in the Premier League.
Confused? I've no doubt David Letterman is.
