A new ad from the National Flossing Council imagines that the Mars Curiosity Rover found dental floss on Mars, providing proof that intelligent life once lived on the planet.
The video, which speculates what the flossing Martians might have looked like, was created to bring attention to National Flossing Day, November 23.
This marks the 12th year that Flossing Day, which falls on the Friday after Thanksgiving, has been celebrated in the U.S.
