You've also surely got loads of anecdotes on how not to do it and tales from the coalface from your years in industry.

I'm sure you can sprinkle some of those into the classes to give a little light relief if the students are really finding things too dry. You don't have to go as far as recreating TheDailyWTF. Perhaps use some to provide worked examples of designing yourself into blind alleys and how to get out again, or just to provide awareness of a few real world issues that might come up with whatever topic is the day's lecture.
