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".
