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 pulling a door labeled "push"), Harold is a few years older than the rest of the Arnold crew because he was left back in school a bunch of times. He is also known to eat a lot, as especially exhibited in "Weighing Harold". In the episode "Harold the Butcher" it is learned that Harold has a deep love for meat. Harold's distinctive features are his size, stomach and giant misshapen tooth.

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. Still, Harold is showing signs - faint ones - of becoming a nicer person. He also has a budding relationship with minor character Patty Smith (voice of Danielle Judovitz). 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). He is also frequently heard bursting into tears and crying out "Mommy!" when in pain or defeated.
