Well they usally make some kind of analogy to American football, baseball or hockey even. They'll mispronounce names, be talking when important things are going on, the introduction/lineups are shown during the game, blocking out the bottom part of the screen. When England had their freekick which Beckham scored on, they were talking about how well "Beckham can bend the ball. After all, they made that movie about how well he bends it."
