7x9 - Fat Albert and the Cosby Kids

Rudy's friend Larry returns to town, hoping to get the gang to join him in some fun activities. However, his kind of fun usually leads to trouble. Larry decides to drive the group to the local pool, but the car he's using is not his! After they're stopped by the police, the gang discovers Larry stole the car. They're all placed under arrest and taken to a detention center. All except Larry are cleared of charges, but with their parents' permission, the gang is taken to prison to see what happens to those who break the law. Their experience there and the fact Larry will be serving time again certainly puts a scare in them, making them vow never to break the law.
