"Stuff You Should Know," the Science Channel's new primetime show, sounds like a show we should all be watching. It's based on the hugely popular podcast, downloaded by 5 million monthly.

It features two regular guys trying to explain the secrets of the universe, and the emphasis is on "trying to."

The show premiered on Jan. 19th, and this Saturday the Science Channel will run a marathon of the show.

This morning on "Early Start," hosts Josh Clark and Chuck Bryant explain the allure of their podcast, and explain why it's now cool to be smart.
