Harold McBride

Harold McBride is a supporting character in The Loud House.

Personality
Harold is more level-headed and calm than his husband. He is normally in charge of preparing and serving dinner at the McBride house. He is a skilled chef, especially when it comes to making Clyde's favorite food, swiss chard frittata. One of Howard's nicknames for Harold is "Hare-Bear".

Harold often mistakes Lincoln's comments for jokes, and thinks he is very funny. He tends to use outdated slang, and exclamations involving the word "great," such as "Great good heavens!" and "Great Betty Buckley!"

Season 1
Harold is one of Clyde's dads. He is seen, mentioned and/or referenced in eleven episodes of the first season. He is first mentioned in "A Tale of Two Tables", in which Clyde helps Howard and Harold do their taxes while Lincoln calls him via walkie-talkie. In "Overnight Success", Harold makes his first on-screen appearance. In the episode, he walks Clyde over to the Loud family's house for a sleepover. Off-screen in "Hand-Me-Downer", Howard and Harold go tandem biking and find Lynn's lost BMX bike. In "The Green House", Clyde tells Mrs. Johnson that his parents use solar panels and try not to burn any fossil fuels.

Harold and Howard are the focus of the episode "Attention Deficit". In this episode, it is revealed that Harold played baseball in college. They are also referenced in "Cover Girls", which is one of many episodes to show the mailbox with their family name on it. Harold's chair can also be seen in the dining room at the beginning of this episode.

In "Lincoln Loud: Girl Guru", Clyde says that Howard and Harold call him a great hugger and always compliment his "million-dollar" smile. In "Roughin' It", Howard and Harold stay at the North Valley Bed & Breakfast while Clyde camps outside with Lincoln. They give Clyde many modern appliances and supplies to use. It is revealed in the same episode that Howard and Harold once went on a safari. There, they camped out in a fancy tent with its own veranda.

In "The Waiting Game", Howard and Harold make Clyde wear a hazmat suit to Chandler's sewage party. After Clyde falls off the Tunnel of Love ride in "A Fair to Remember", the carnival manager asks "the parents of a soggy boy" (Clyde) to come pick him up. Howard and Harold do not make a physical appearance, but this line indirectly references them. In "April Fools Rules", Clyde tells Lincoln that he and his dads have to keep their cat Cleopawtra in a crate when she gets "feisty."

Howard and Harold's tandem bicycle appears in "Butterfly Effect", although neither of the dads were seen in the episode. Their house and chairs once again appear without them in "One Flu Over the Loud House".

Season 2
Harold will appear in two of the three first episodes in Season 2. He will be present for the series' holiday special "11 Louds a Leapin'". He will be the focus of "Baby Steps", in which Clyde thinks he and Howard are going to have another baby.

Other
In a live stream from the Nickelodeon Animation Studio Facebook page, Miguel Puga drew Howard and Harold.

Appearance
Harold has dark skin and black hair. His hair appears to be thinning and is very short compared to Howard's. Harold bears a resemblance to Clyde. He wears a blue/teal sweater vest with a black bow tie and a light blue shirt underneath. He also sports a pair of jeans and brown loafer shoes.

Clyde
Clyde and Harold are very close. Since he is the chef of the house, Harold always packs Clyde's lunches. It is possible that Clyde is Harold's biological son, due to their nearly identical hair and skin colors. Harold is the only character who has called Clyde "son."

In "The Loudest Yard", Clyde is shown to be a good baseball pitcher, so it is possible that Harold taught his son how to play.

Howard
He is shown to get along with his husband quite well, though he usually has to calm his husband down when he gets too emotional as shown in "Overnight Success". The two are shown to have similar hobbies and enjoy each other's company, rarely being seen without the other and the two seem to love each other dearly, with Howard calling Harold "Hare Bear" in "Attention Deficit".

Lincoln
Harold seems to be closer with Lincoln than Howard is. He always laughs at Lincoln's jokes. Whenever Lincoln visits the McBrides' house for dinner, he sits in the chair next to Harold's.

Leni
Harold helps Leni with her makeup in "Attention Deficit" and does a surprisingly good job. Leni appreciates his help.

Lynn
Harold and Lynn share a love for sports, particularly baseball. Harold has helped Lynn practice her catching skills.

Trivia

 * The colors and styles of clothing that the Loud and McBride parents wear correspond with each other. Harold and Lynn Sr. both wear sweaters and brown loafer shoes. They also both have thinning hair.
 * Whenever the Loud House social media accounts refer to Howard and Harold as Clyde's dads, "Dads" is capitalized like a proper noun.
 * In Lincoln's dream in "One of the Boys", every character's gender is swapped and there is a female version of Clyde. It can be inferred that Girl Clyde would have had two moms (female Howard and Harold).
 * Harold has had more lines throughout the series than Howard has.
 * In "One Flu Over the Loud House", it is shown that the McBrides have peanuts in their kitchen. Since Clyde is allergic to peanuts, this must mean that Howard and/or Harold can eat them.
