Maybe off-topic but,
If you're not familiar with the CMU DB Group you might want to check out their eccentric teaching style [1].
I absolutely love their gangsta intros like [2] and pre-lecture dj sets like [3].
I also remember a video where he was lecturing with someone sleeping on the floor in the background for some reason. I can't find that video right now.
Not too sure about the context or Andy's biography, I'll research that later, I'm even more curious now.
