"The term "Shotgun" refers to the front passenger seat of an automobile. Calling "Shotgun" is the act of claiming the position of Shotgun for one's self. As this position is the most coveted of all positions when riding in a car, the following list of rules has been created to ensure that Shotgun can be acquired in a fair and equitable manner by any passenger of an automobile."
"The History The history of calling "Shotgun" goes back to the days of covered wagons and the Wild West. On a trip across the plains, the driver of a wagon would hold the reins of his horse team and concentrate on driving. This left him and the occupants of his wagon susceptible to sneak attacks from bandits and thieves. To avoid this atrocious circumstance it became necessary for one person to sit next to the driver with a shotgun and fend off the enemy.
In modern times, defending against bandits is no longer the main objective of riding Shotgun, but the ritual of calling Shotgun has evolved into a pre-driving ritual that is experienced before almost every car ride in America and around the world. After considering the obvious evolution that Shotgun has already experienced, we ask you to consider Shotgun a living entity and be aware that it is always changing for the better good of society."
I suggest you all learn the rules, become familiar with the concept, and appreciate the higher success rate of your shotgun calls.
