I recall a time when Google's SVP of Engineering saw some of us in 
  the cafeteria and congratulated us on a release; this was surprising 
  since we hadn't released anything recently, and it soon came up that 
  he thought we were working on the Dart language, not the Go language.

That's a great little story. As an IC, I always felt that VP's, Staff, etc would know everything about what was going on in their organization. This story lets me know that even at that level, they don't know everything.
