In the event that someone has called "jack jack" to get their "seat back" there is a single loop hole. Each location, (house, car, airplane, really anyplace there is a seat) is allowed a single 'Doctored Through" call per 24 hours. This call overrides all other previously stated calls, or "dibs".
Kyle "SHOTGUN! I total got you good fucker, you going to have to sit in the back seat all the way to Missoula!"
Darren "Fair enough, oh by the way, SHOTGUN DOCTORED THROUGH! BYOB Bring your own booya baby! Now get your ass in the back seat!."
