Hey Harold! is an episode of Hey Arnold!.
Harold, who usually hates girls, goes to Rhonda's party even though he thinks he'll look stupid. He meets Patty and at first they argue about which gender is dumber, but then they realize they have a lot in common. The next day they go out on their first date and agreed to sit next to each other at lunch. However, Stinky and Sid tease Harold for developing a crush on Patty, so he doesn't sit next to her at lunch to prove he doesn't like her.
Then at lunch, Sid and Stinky make fun of Patty by calling her clumsy at dancing. Harold snaps at them and tells them to mind their own business.
Then he sits next to Patty and they eat lunch with smiles on their faces.
