Shaving can be a difficult ordeal for any man, but imaging if you were Superman. Would it be as simple as picking up a set of clippers and getting your shave on, or is it a bit more complicated for the Man of Steel?

The folks at Gillette would like to believe so. In an effort to promote the summer’s upcoming blockbuster hit Man of Steel, Gillette created a ‘How Does He Shave’ series, asking comic book fans everywhere to offer their theory of how Superman cleans up. Our fave pick has got to be by the world’s favorite science guy, Bill Nye. The man who has broken down just about every science theory known to man, now explains how one of our favorite comic book hero shaves.

Be sure to also check out a few other videos by actor Kevin Smith, the hosts of Myth Busters, and actress Mayim Bialik below. And head to the Gillette website to vote on your favorite theory.
