What are you talking about? Queens is a borough of New York City and a county in New York State, one of two on Long Island (the other is Brooklyn which is closer to Manhattan, Brooklyn is sometimes known as Kings County but nobody calls it that). Queens is probably one of the most ethnically diverse places in the world; over 150 languages are spoken there.
King of Queens was a TV show starring Kevin James about a man and his wife who lived in Queens. Hence the king of Queens.
