The Case of the Broken Record - S1.E19

For Tina's '60s dance Fred is going to teach her the twist, but the record is broken in two. Fred and Casey automatically blame the kids, and try to find out which one did it. Someone comes down during the night and replaces the record with a new one. The adults lecture the kids about the record, and trick Tina into confessing to replacing the record, but not to breaking it. Then Turner says he broke the record but he really didn't. It turns out the record was broken by an explosion from the lab, so Fred and Casey owe the kids and apology.
