This is a commercial for the Science channel's 'Through the Wormhole' featuring Morgan Freeman (who also hosts the show) talking on helium. Don't even act like you haven't waiting your whole life to hear what this sounds like. Now I can die happy. Hopefully in my sleep, but probably doing something my mom always told me not to.
Keep going for the video.
Thanks to Jess, who agrees Christopher Walken should go next.
