Gillette's 'How does Superman shave' clip goes viral

Razor maker Gillette launched a video campaign Tuesday asking the logical question of how Superman could possibly shave in the upcoming film 'Man of Steel.'

To answer the philosophical quandary, the shaving company recruited several celebrity nerds to advance their theories, the New York Daily News reported.

"Spoiler alert," says Bill Nye, aka the Science Guy, in his video. "Superman has gotten a beard in the beginning and he doesn't have a beard a little ways into the movie, so there's some means of shaving."

His theory - Superman grinds the hair off rather than cuts it. That would require less actual force.

Director and comic book store owner Kevin Smith also weighed in, quickly nixing the idea of a Kryptonite razor.

"Would you shave with death, ladies and gentlemen?" he asks the camera, referring to Superman's vulnerability to minerals from his home planet. "Of course not."

Instead, he "stakes his reputation" on the theory that he uses part of the rocket pod in which he rode to Earth as a baby.

More probable is actress Mayim Blalik's postulation - she does have a Ph.D. in neurosicence, after all - that is most basically described as her "enzymatic follicle denaturation theory." Or in nongeek speak, a scientifically devised lotion to remove the hairs from the follicles.

Jamie Hyneman and Adam Savage, hosts of TV's "Mythbusters," hedged their bets with multiple ideas - including using the Hadron Collider to create tiny wormholes that suck out each individual stubble hair into another dimension.
