I can confirm that this is a reference to an entertaining internal video with Fox Girl and Broccoli Man. Fox Girl just wanted to serve 5TB of data and Broccoli Man was explaining the many, many steps of configuration, services, and monitoring that were required to do this at Google. I agree with scottlamb; I only heard "I don't know how to count that low" in reference to the video, not as a "sign of superiority" that the post describes.
I wish I had taken a picture of that shirt before it had been run through the wash a few times. It used to look a whole lot better!
But yeah, that video was epic, and it was spot-on, too. A company that has no idea how to deal with people is going to suck at making tools _for_ people.
The video was also described briefly here: https://rachelbythebay.com/w/2012/04/06/5tb/
