An English visitor to the United States was taken by a work colleague to his first football game, one that also happened to be being screened live on TV. Afterwards his host family asked him whether he had enjoyed it. "Not really," he admitted. "I found it boring. It was all very stopstart. Every thirty seconds or so, the referee would blow his whistle, and the game would then take a few minutes to resume." "Well, you know why that is?" "No." "Snack breaks for the audience."
