The King of Queens is a classic. The cast was awesome, and it was really an enjoyable show to watch (until the last few episodes of the final season when the story got a bit wonky).
Jerry Stiller made that show... his character was the perfect compliment to Kevin James, Leah Remini and the rest of the cast.
Jerry's wife, Anne Meara played Spence's mother, Veronica Ulchin, and their daughter Amy (Ben Stiller's older sister) played several roles, too. She was the video store clerk in one episode, the coffee shop employee in several and other random roles, too.
Also, Gary Valentine, who plays Doug's cousin Danny is actually Kevin James' brother.
