I remember watching a talk of Bob's where he pumped up how good his approach to coding was, and when asked to provide examples, he could/would/did not provide any. Seriously, if you can't demonstrate what you're talking about, I'm just gonna take you less seriously.

I think it was this video, but I can't watch it all the way through right now -- https://youtu.be/ecIWPzGEbFc
