Hey Arnold! Season 3 Episode 14 - Arnold's Thanksgiving Episode Title:Arnold's Thanksgiving.Episode Description:Arnold and Helga are sick of their families' Thanksgiving traditions. Arnold's grandma confuses Thanksgiving with Fourth of July, and vice versa, so his Thanksgiving meal consists of hotdogs and watching fireworks. When the others will not help him convince Gertie otherwise, he leaves. Helga is upset that her family ignores her, even on Thanksgiving, with Olga forcing everyone to help with the meal, then taking all the credit. Miriam ignores Helga's handmade centerpiece in favor of Olga's, and Big Bob just wants to watch the football game. Helga leaves when her family puts her down for having nothing to be thankful for. They meet and go to Mr. Simmons', only to realize that, compared to Thanksgiving with his family, theirs are not so bad after all. Arnold returns to a turkey and fireworks, Helga returns to a frantic family, who are on the phone with the police and making flyers to find her.
