I love this "stream of consciousness" teaching approach for a podcast.  I may need to try a similar method in the future, since I talk to myself all the time already while tinkering in my shop. 

The idea of angry pixies is a fun one, which works well enough to communicate the ideas.  They may have been influenced a tiny bit by the mulled wine. :)  Hmmmm...  Maybe mulled wine would have helped me through my college electronics classes (Especially transform analysis!)

Keep up the awesome work, and have a happy new year.
