Trivia: It's in this episode that the Heimlich Maneuver is used for the first time by the paramedics. At the USC game, when a guy is choking on a hot dog, John and Roy are called, and John uses the Heimlich. Up until season 6 we've seen the guys use other methods, such as the ChokeSaver which look like huge white tweezers, to remove obstructions in an airway, as seen in 4x9, "Foreign Trade."
