You need to see this video of Morgan Freeman on helium

Why has no one done this before?

This is one of those videos that you didn't even know you needed - Morgan Freeman on helium.

Freeman has one of the most distinctive voices in the world - so it's pretty damn hilarious to hear his smooth, deep tones go all high-pitched and squeaky.

The veteran actor inhales the helium gas from a big red balloon in a trailer for US TV show 'Through the Wormhole', which will try to explain some of the universe's greatest mysteries.

Surely one of the world's greatest mysteries is why no one gave helium to Morgan Freeman before now?
