Harold vs. Patty is an episode in the Hey Arnold! TV Series. It is also known as Harold and Patty Arm Wrestle.
Harold and Patty compete in an arm wrestling contest. Harold is beating everyone in the school, and is considered the arm wrestling king. However, before the contest, Harold and Patty practice, but Harold loses after the count of three, and everyone makes fun of him because he got beat by a girl. Arnold then helps him practice for a day, but Harold doesn't care about practicing. He has a rematch with Patty, but loses again. Harold is embarrassed, so he begs Patty to help him win, but not lose on purpose. They train and train. At the contest, Harold and Patty compete against different kids, and in the finals they end up against each other. Harold is doing better, but like last time, Patty beats Harold, and Stinky and Sid still make fun of him. But Harold doesn't mind that a girl beat him, and says girls can be tough too.
