All five of us are basically obsessed with YouTube -- even our two-year-old clamors for "more funny bideo!" whenever she sees a computer. I am, however, at least vaguely aware that other families may not sit around browsing YouTube with their kids every single night. So it occurs to me that some percentage of you may have missed what is (in our view, anyway) possibly the coolest ad ever. And yes, I know it's two years old -- but it still gets at least three views per day at our house. Every day.
