Curly (Hey Arnold)

Thaddeus Gammelthorpe, better known as "Curly," is a fictional nerd on the Nickelodeon cartoon Hey Arnold!. He usually plays a minor role.

Personality
Curly is known for being the fourth grader "most likely to snap" by his peers. He once locked himself in Principal Wartz's office and threw handballs at everyone because he didn't get his beloved "Ball Monitor" role. He also has covered himself in war paint and freed animals from the zoo for no particular reason. Curly is a fan of opera and ballet, as seen in several episodes. In "School Play," he was cast as Mercutio in "Romeo and Juliet." He has also pulled the school's fire alarm at least twice.

Like most minor fourth graders on Hey Arnold!, Curly's parents are very rarely, if ever, shown.
