The 600 Club

Yesterday, I was driving behind a car that had a license plate holder that read "600" on the top, and beneath it said, "HE IS IN ME." Couldn't make it out for the longest time. What was this mysterious 600 that was in the driver of the car? Puzzled about it for a good long block, tailgating the driver mercilessly and racking my brain for some 600 cult or extra meaning that would make sense of the thing. Finally figured out that 600 was, in fact, the letters G-O-D in very blocky font. A worthless story, but it amused me nonetheless.
