It's a show in which two men just have fun and explain about different types of science stuff. I think it was aired on Nat Geo, though I could be wrong. The time period of this show could be close to 2010.
At the end of every episode one of the men cuts something in half to explain how it works while showing its insides. One time he tried to cut a engine but couldn't. In another episode, they showed how to beat a lie detector.
Its intro or outro contained a scene in which their lab coats were cut off from their body.
