The idea of working 80 hours a week means you’re doing
  something really inefficiently, or you’re just warming
  your ass at the office on Facebook, Twitter or Youtube.

I've seen this so many times!

A friend of mine told me his employer's solution was this: Block all three, along with Reddit, imgur, and the likes. Then only allow one public computer with unrestricted access. This one computer is on a standing desk, in a busy hallway.

I didn't think it would work with the prevalence of smartphones, but apparently it has. Having unrestricted access from all desktops just made it too easy.

It's a shame humans don't have more self control.

I hope the people who ordered weren't too excited about his product.
