Nick: Hey Arnold! Trivia Quiz

Answer: 33

Arnold's best friend, Gerald, is most of the time seen with a red T-shirt with a 33 written in white numbers. The meaning of these numbers is unknown but probably it was just a random choice.

Answer: Abner

Arnold, unlike many other children, owns a pig, which happens to be a present to his parents from the Green-Eyed People (as featured in the episode "The Journal").

Answer: Eugene

One common gag in "Hey Arnold!" is Eugene's bad luck and the terrible events which happen around him. Among these events are dog attacks, destruction of his belongings (for example, his bicycle) and falling accidents.

Answer: Phoebe

At first, Arnold's love interest was Ruth, but in later seasons, he had his eye on Lila. Helga is also in love with Arnold, but he apparently doesn't know.

Answer: Phil

Since his parents disappeared misteriously on a rescue mission to the island of San Lorenzo, Arnold was left under the care of his grandparents: Phil and Gertie.

Answer: Phoebe

Phoebe is to Helga as Gerald is to Arnold and, curiously, Phoebe and Gerald are attracted to each other.

Answer: Stella

Bob and Myriam are Helga's parents and Olga is her "perfect" sister and, also, the favorite daughter. Stella is actually Arnold's mother.

Answer: Dino Spumoni

Dino Spumoni used to live in Arnold's house, but he became a millionaire and moved out. Dino, however, turned into a solitary man after several years of success in the music business.

Answer: Beardman

The correct form of the incorrect "Beardman" is "Berman" (Harold's surname). Pataki and Johanssen are Helga's and Gerald's surnames respectively.

Answer: Potts

Potts is actually Ernie's surname. All the others were, at some point, Arnold's teachers. Mrs. Slovak was his first teacher but she was replaced with Mr. Simmons after she quit. Miss Felter was a one-episode substitute teacher.
