7x13 - Fat Albert and the Cosby Kids

Weird Harold finds a lost wallet and does the right thing by returning it to its owner, who runs the local arcade. Mr. Sherman rewards Harold with enough cash to play his favorite Brown Hornet video game. He eventually becomes obsessed with the game to the point that he borrows the gang's lunch money, then steals the money they were raising for a picnic they planned with their teachers. The gang eventually confronts Weird Harold at the arcade where he's faced with having to pay them back. Mr. Sherman allows him to work there so he can raise the money so they can have the picnic after all. Weird Harold learns a valuable lesson in moderation.
