Harold Berman

Harold Berman (voiced by Justin Shenkarow), is a fictional character in the Nickelodeon animated television series Hey Arnold!. Big, mean, and stupid (in "The Aptitude Test", he tried pushing a door labeled "pull"), Harold is a few years older than the rest of the Arnold crew, because he was left back in school a bunch of times (so he claims, at least). He is also known to eat a lot, as especially exhibited in "Weighing Harold", in which he puts on an enormous amount of weight. In the episode "Harold the Butcher" it is revealed that Harold has a deep love for meat. Harold's distinctive features are his size, stomach and giant misshapen tooth. He is usually seen with Stinky and Sid. When they get together, they can do some crazy stuff, like mooning principal Wartz in "Full Moon".

Harold's the kind of guy who you can never really trust - one day he'll be on your side, the next day he'll probably come back and beat you up - or taunt you by saying your name over and over and over again in baby-talk. Harold often gloats of his own intellectual or physical superiority, though usually seconds later proving himself wrong or being shown up by another character. Still, Harold is showing signs - faint ones - of becoming a nicer person. He also has a budding relationship with minor character Patty Smith (voiced by Danielle Judovits). He is of the Jewish faith, revealed when he invited the other students/friends to his Bar Mitzvah.

Harold acts tough all the time, but is occasionally shown having a sensitive side (though he denies it in public). When in pain or defeated, he is usually heard bursting into tears and crying out "Mommy!". He may also not be as unintelligent as he leads himself to believe. His attendance at the fourth grade, despite his age of 13 years, appears to be strange due to various facts: Harold is seen during several flashbacks dealing with kindergarten events of Arnold's age-group. Being in the same preschool class with the other kids, Harold had to be held back from kindergarten. Considering that Harold might be in fact highly intelligent, this seems to be even more implausible. In "The Aptitude Test" an accidental mixup in test results suggests he may be a genius (rather than Helga, who got his lousy test scores in exchange), resulting in him striving to remain true to this fact. But neither before, nor after the events of this episode, Harold shows any outstanding intellectual skills.
