There are three things going on in this episode:
1. Dr. Elbie gets into a discussion of how Yes/No Charts modify behavior;
2. There is a Keystone Kops situation that gets everyone yelling at each other, and;
3. Dr. Elbie gives Mr. Grimes his first lesson of the War on Waste Paradox using the previous day's Keystone Kops situation as a good basis to start the discussion.
Good things are starting to happen.
