<Li> Daniel "Danny" Heffernan (played by Gary Valentine) is Doug's cousin, and he is also seen hanging out with Doug, Deacon and Spence . In the show's early seasons Doug has a negative view of Danny bordering on hate due to the latter's overeagerness to spend time with the former, but at the end of "S'no Job", they become friends and co-workers and regularly hang out along with Deacon and Spence . Danny even becomes Spence's roommate in a small apartment . The two fight like a married couple, and many of the jokes revolve around what looks to their friends like a romantic relationship . At one point, they legally marry in order to get a free TV from a sales pitch for which only married couples are eligible . Danny also used to own a pizza place, and he is divorced from a woman named Eva . He once had the nickname "Stumpy", which was given to him by Doug . Episodes "Silent Mite" and "Paint Misbehavin"' reveal that Danny has asthma and uses an inhaler . Gary Valentine and Kevin James are brothers in real life . They both created last names for acting . Valentine is their father's middle name . </Li> <Li> Holly Shumpert (seasons 3--9; played by Nicole Sullivan) is a polite, yet timid dog - walker who along with the Heffernans lives in Queens, where she was hired by Doug and Carrie to walk Arthur . She is often seen arriving at the Heffernan house to pick up Arthur but is also a family friend of the Heffernans . She is often viewed as strange because of her habits, the men she dates and her habit of overdrinking, to which she openly confesses . Holly is a gentle soul, especially as she puts up with Arthur's antics, and is kind to Carrie despite the fact that Carrie often mistreats her . Holly was written out of the series at the beginning of season eight, but she later returned, pregnant, for one last appearance in the series finale ("China Syndrome"). Sullivan appeared as a different character in the season 3 episode "Pregnant Pause". </Li> <Li> Sara Spooner (season 1; played by Lisa Rieffel) is Carrie's younger half - sister, an irresponsible aspiring actress . She appears in only five of the first six episodes . She was only mentioned one other time (although not by name) in episode 52 ("Roast Chicken") by Doug as an excuse to his boss to get out of performing a roast . After the show became more popular, Kevin James was asked to explain what happened to Sara during an interview . According to James, the producers could not think of any storylines to develop Rieffel's character, so she was discontinued . During the pilot she was on camera for roughly half the episode . However, in the other episodes in which she was included, her character did not have much to say or do . Subsequent dialogue suggests that Sara Spooner never existed, and that Carrie is an only child . (The disappearance of her character, coupled with the show's subsequent contention that the character never existed, is an example of the "Chuck Cunningham Syndrome".) </Li> <Ul> <Li> Kelly Palmer, Deacon's wife (played by Merrin Dungey) is Carrie's best friend . She has two children with Deacon . Kelly and Deacon experience some serious relationship problems, much more serious than the petty arguments between Doug and Carrie . On one occasion, Deacon mentions being hit in the head with a frying pan . She was absent from the show in 2002 because she needed to take a break from the series; during this period, her character was estranged from Deacon and engaged in a brief affair . </Li> <Li> Lou Ferrigno (seasons 3--9; himself) is the actor known for his role as The Incredible Hulk . Ferrigno and his wife are neighbors of the Heffernans . A running gag on the series is that the neighbors (including the Heffernans) are fascinated by him and it gets on his nerves . Lou does not like people telling him Hulk jokes . Other characters often make reference to his previous role as the Hulk . For example, at one point Doug is angry and Lou tries to calm him down; Doug retorts with the famous line from the Hulk series "Don't make me angry; you wouldn't like me when I am angry". Also, in the episode "Gym Neighbors", it is revealed that he has a video game addiction . </Li> <Li> Supervisor Patrick O'Boyle (seasons 3--9; played by Sam McMurray) is section supervisor for the fictional International Parcel Service . He is Doug's boss and friend throughout most of the show, whom he mostly refers to as "Heffernan". He is in most IPS scenes throughout the show . He is also a recovering alcoholic and gambling addict . A character named Supervisor Jack O'Boyle (played by John F. O'Donohue) appears in an episode from season one ("White Collar", 1999). </Li> <Li> Raymond "Ray" Barone (seasons 1, 2 & 8; 5 episodes; played by Ray Romano) is Doug's Long Island friend . Romano and James appearing on each other's shows was part of a network program crossover, as CBS aired both Everybody Loves Raymond and The King of Queens . Romano's appearance was successful enough to warrant all other lead characters (Patricia Heaton, Brad Garrett, Doris Roberts, and Peter Boyle) to appear as their respective characters as well . Appropriately, the four episodes featuring Romano contained "Ray" in their titles ("Road Rayge", "Rayny Day", "Dire Strayts", and "Raygin' Bulls"). </Li> <Li> Doug Pruzan (season 2--6; played by Alex Skuby) is Carrie's boss and a lawyer at a Manhattan law firm . </Li> <Li> Veronica Olchin (season 1; played by Grace Zabriskie, seasons 5--9 played by Anne Meara) Spence's mother . She is portrayed by Zabriske in her first appearance in "S'aint Valentines", but portrayed by Meara for the rest of the series . Veronica has an on - again / off - again relationship with Arthur, who is portrayed by Meara's real - life husband, Jerry Stiller . Meara had previously appeared in "S'aint Valentines" as a woman who flirts with Arthur . Arthur and Veronica marry in the series finale, but divorced a year later . </Li> </Ul>
