User blog comment:ABCDude/The Mysterious Football Zombie/@comment-3541906-20120112101524

Football is two different things: A Ball and A game which is played with the ball. The Suburban Almanac says: "He has no idea what a football is." Note the 'a football' there. It means almanac is not talking about the game. He don't know what 'a football' is. But as he says: "I used to play football" means that he knows how to play the game 'football'. Alamanac is referring to 'a' object, football. And the zombie plays the game, football. Easily understood now??
