»In which I convert to Baptism, so as to guarantee a parking spot for when I go to meet the Lord

These parking permits seem easy enough to make, but the city's seal of authority appears only if they are held by double-parking Baptists. What is the story with their ability to block in everyone else on the street? To block one lane of traffic on Guerrero and Dolores? What secret covenant does the City of San Francisco Department of Parking and Traffic have with Baptists that allows them to flaunt the law? I know that they are not members of this community, otherwise they would not be driving and double-parking -- they would easily walk or bike in their Sunday best. Nothing on the DPT's web site suggests that Baptists should receive special traffic-buggering privileges. Were I Presybterian, could I obtain a similar permit? Quaker? Hindu? et c.
How do people blocked in by Baptists get out? If they call the DPT, does the dispatcher say, "Oh, worship of The Lord (praise his mercy!) is part and parcel of Sunday in San Francisco"? does the metermaid drive up in the Interceptor, fall to his knees and speak in tongues? What arcane interaction between San Francisco and the collected Baptist Churches makes this possible?
