"Shotgun" rules

From the department of "I didn't know that" comes the Shotgun Guide, a list of rules for calling "shotgun."

I especially like rule #6 under Section II, Special Cases:

In the instance that one of the occupants is too wide or tall to fit comfortably in the back seat, then the driver may show mercy and award Shotgun to the genetic misfit. Alternatively, the driver and other passengers may continually taunt the poor fellow as they make a three hour trip with him crammed in the back.
