Harold McBride is a supporting character in The Loud House.
Harold is more level-headed and calmer 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. A pet name Howard has for him 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 He tends to use outdated slang and exclamations involving the word "great," such as "Great good heavens!"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!"
Harold used to play baseball when he was in college. He is still able to play, but is obviously not as athletic as he used to be. Harold owns multiple sweater vests and bow ties in different colors, one of them being holiday-themed.
Harold is one of Clyde's dads. He is seen or mentioned in ten 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.
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".
Harold appeared in two of the three first episodes in Season 2. He was present for the series' holiday special "11 Louds a Leapin'". "Baby Steps" was another episode that focused on them. In it, Clyde thinks he and Howard are going to have another child. It ends up being a misunderstanding and they were actually getting another kitten for him. At the end of the episode, Howard and Harold decide to go out together while they let Clyde practice his big brother skills.
In "The Whole Picture", it is revealed that Howard and Harold back up all of Clyde's childhood photos with their online cloud storage. Clyde also mentions that he and his dads hold acting sessions every Friday. In "Cheater by the Dozen", Clyde says that he is not allowed to watch R-rated movies, further showing how his dads treat him like a baby. Although the episode takes place mostly at the McBride house and the dads' tandem bicycle is seen, they do not physically show up at all.
In "Kick the Bucket List", Howard and Harold surprise Clyde by going on an eight-day vacation in Hawaii. They go on a plane, visit a volcano, go sailing, and swim in the ocean. Throughout the entire trip, Clyde tries to trim down the list of activities he planned to do with Lincoln over spring break. This leaves him distracted, so Howard and Harold have to continually save him from danger he is unaware of: they pull him away from lava when visiting the volcano, catch him when he nearly falls overboard on their sailing trip, and take a fish off of his head when they go swimming.
Harold and Howard are mentioned in the compilation short "The Many Sides of Clyde McBride." In a 2016 live stream from the Nickelodeon Animation Studio Facebook page, Miguel Puga drew the Dads. They are also drawn by Chris Savino in a live stream from February 2017.
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.
