Arnold's Thanksgiving is a special half-hour episode of Hey Arnold!.
Arnold and Helga are tired of their respective Thanksgivings, so they decide to enjoy dinner with Mr. Simmons, but it's less magical than they would have imagined.
Arnold's grandmother celebrates the Fourth of July when it's really Thanksgiving, which is not what he had in mind for the holiday. Meanwhile, Helga's optimistic hopes are squelched when her mom tells her to put her pine cone table piece she made next to Olga's ice sculpture of a turkey. This annoys Helga, who doesn't bother displaying her table piece. She becomes increasingly unhappy when she has to put up with helping Olga make dinner, Big Bob watching football, and a usual drunk Miriam. When Arnold has had enough of dealing with his family's way of celebrating Thanksgiving, he decides to leave. At home, when Helga bluntly states she is thankful for nothing when having her Thanksgiving dinner with her family, Bob sends her to her room. She decides to leave her house as well.
Coincidentally, Arnold and Helga run into each other and start talking about how things at home aren't working out. During this time, Helga's family notices her absence and becomes increasingly concerned about her whereabouts. As the day progresses, Helga's family takes to the streets (Olga posting flyers) and starts looking for her. Eventually, both Arnold and Helga go to Mr. Simmons's house in search for the perfect Thanksgiving, only to find out that his isn't going so well either. After they leave Mr. Simmons's house, they realize that their Thanksgiving wasn't as bad as they thought and return to their homes. When Arnold gets home, he embraces his grandmother's Fourth of July celebration and Helga's anxious family warmly greets her with a loving embrace. The Pataki family also places Helga's pine cone place setting back onto the table next to Olga's and sit down together to eat dinner.
- This episode gained a large amount of controversy in May 2016 after a Vine (that was posted in 2013) became viral, which showed a clip from the episode that supposedly depicted anilingus. Craig Bartlett ultimately denied this scene (after being forced by the internet) was depicting anilingus in a recent news article on May 26th as it was actually Chuck eating turkey.
