6 feet tall here. Hasn't helped a damned bit. But then again, I'm Asian so even if I were a CEO and ran 3 charities, it probably still wouldn't have helped.

I first heard the term from the book "Dreaming in Code" by Scott Rosenberg. If you think about it though, it makes sense. It's where you eat the food (test/use the product) that you're about to serve to the dogs (users). It's supposed to give the connotation that your product is still in an untested (crappy) phase.
