Most of us like to believe we are on top of most things. We have heard the latest song, seen the latest celebrity news or watched the latest show. I, for the most part, believe I'm on top of most stuff like that.

Here's a video, however, I had never seen before. It's a public-service announcement with more than 50 of the countries' top celebrities, from Conan O'Brien to Jennifer Aniston to Beyonce. It packs a pretty powerful message into a minute.

The sad thing? This video was posted over a year and a half ago. And I hadn't even heard of this. Only 7 million views on YouTube. Let's get that up to 70 million.
