Harold (Billy & Mandy)

Harold is Billy's dad and the wife of Gladys.

Personality
Like Billy, Harold is very stupid and is prone to do stupid things. It seems he is an expert in dancing in the episode Billy Idiot, he beat the Mrs. Pollywinkle, who was Billy's dance teacher. He sees Billy as a genius due to the boys' "genius" when Billy was young and tries to get others to see this too, as seen in The Problem with Billy, much to Billy's irritation. Despite this, he still gets annoyed sometimes by Billy's antics. He is afraid of Santa Claus and his wife, Gladys, who is mentally unbalanced.

Harold is a voracious eater, and willing to eat anything. He once said that he was still so hungry after eating two breakfasts that he couldn't wait til lunch and so knowingly ate his wife's mucus covered pet rat live. He also ate his wife's goldfish as well but with a different reason that only his wife heard and not Billy, Mandy, Grim or the audience.
