. . . years ago.
One of his customers was an LAPD motorcycle cop who worked the Hollywood beat for a while. Late one night, a convertible driven by a black gentleman whizzed by, so he pulled him over for speeding. After running the guy's license and checking his car out, he turned to the driver and said, "I'm letting you go with a warning, on one condition. It's 3 AM. Why are you wearing shades?"
"When you be cool, man, the sun is always shining."
