Gertie (Hey Arnold!)

Gertrude is Arnold's grandmother from the Nickelodeon Nicktoon Hey Arnold. She is the wife of Arnold's Grandpa Phil, and they have known each other since childhood. They had a relationship like Arnold and Helga when they were young. Gertie was mean to Phil (although in more extreme ways, like putting thumbtacks in his seat, dunking a part of her hair in ink and telling the teacher Phil did it, etc.) Grandma Gertrude runs a boarding house with Phil. Most of the boarders think she is crazy, because in every episode, she has a different theme that can be seen in her clothes, the way she talks, and the food she prepares for the boarders. She often is used as a philosophical source, especially with Arnold, through the use of metaphors that are usually not understood.

Gertrude usually acts younger than she appears. She taught Arnold karate in one episode and helped him save a turtle from the constant torment from the elementary school children in another episode. She is often the only person who understands Arnold.

Grandma Gertrude and Grandpa Phil are the parents of Arnold's dad, Miles.

Grandma Gertie is voiced by Tress MacNeille, who is also the voice of Charlotte Pickles on Rugrats and All Grown Up!, two other Nicktoons.

Examples of Grandma Gertie's wacky outfits and acts include the following:
 * In "Eugene's Pet", Grandma Gertie dresses as a mermaid and serves fish.
 * In "Arnold's Thanksgiving," Grandma Gertie gets the entire family to dress as important figures in American history in celebration of the Fourth of July. It's noted that she celebrates Thanksgiving on the Fourth of July. However, in the end, it ends up a normal Thanksgiving (with fireworks).
 * In "Parents Day," Grandma wears her karate outfit throughout most of the episode, and is cooking miso soup.
 * In "Summer Love," she sees a nudist beach. She then takes off her suit to join the nudists, scaring them away.
 * In "Family Man," she dresses as Mary, Queen of Scots. While Mr. Hyunh is pretending the boarders are his immediate family, she pretends she's also Mr. Hyunh's sister.
 * In "Teachers Strike," she dresses up as a Spanish Conquistador and gets on top of the table saying "I claim this dinning room in the name of Spain" while every one in the boarding house is having dinner.
