The four suspects pulled over by the police officers tell Commissioner Scali they are signers, which he doesn't necessarily believe. However in reality, they are all members of The Main Attraction, which evolved from a group singing a'cappella on street corners in Seattle's Pioneer Square to an international class act whose show stopping harmonies are truly one of a kind. They have opened shows for Smokey Robinson, The Four Tops, Eddie Murphy, Helen Reddy, BB King and Natalie Cole just to name a few.
Many people may wonder the same as I have if Michael Chiklis went bald naturally. Turns out it was anything but natural. At a younger age he was in a play or theater production playing a 65 year old man. Instead of using powder to make his hair gray, he used grease paint and did not remove it completely and correctly. Apparently, the grease paint killed off almost all his hair follicles, so that's why he has kind of a "Mr. T" bald look. This is documented in any number of internet searches.
