The entire show was hilarious, one of the funniest TV shows I've ever seen. They revived the concept years later as "The Naked Gun" movies, but as the original concept was a spoof of various crime TV shows and all its conventions, including freeze frame endings, guest stars, stock footage rear projection, etc., the format worked better as a TV show.
Yes, the show was way ahead it seems. It was officially canceled because people actually had to watch it to appreciate the humor (the show wasn't just silly, but also fast and smart), which TV Guide later called one of the stupidest reasons ever for canceling a show.
One of my favorite characters was the shoe shine guy, who was not only an informer for the police, but apparently so knowledgeable, everybody from surgeons to psychiatrists to fire departments consulted him.
