Nick Offerman shocked the world over the weekend by stepping out sans mustache. Somehow he just might look even more manly with a chinstrap beard, but nevertheless it's jarring to see Ron Swanson without his signature lip whiskers. Offerman, of course, isn't the first celebrity to shave off his iconic mustache. Below are some other notable names who have rendered themselves close to unrecognizable by breaking out the razor after a legendary career of mustache-having. It's hard to say which look suits them best, but either way they'll be remembered for their facial hair. If you happen to want to do the opposite and actually grow a mustache, here are some fine examples we endorse.
