McCarthy had plenty of interests, and he would easily discuss them at great length on his morning show, and generate a little criticism in the process. One of McCarthy's passions was golf. He played it frequently as an adult and was an authority on the game and its rules. He belonged to multiple private country clubs, and for a time served as president of the Bloomfield Hills Country Club. He had PGA golfers on his show and broadcast his show from many golf tournaments. One annual event that was dear to him was the annual fundraiser of the Detroit Police Athletic League, where he persuaded professional golfers to participate in pro-ams.
