Hollywood heartthrobs like Brad Pitt, George Clooney, Mel Gibson and even Jude Law have been spotted with the funky facial hair in recent weeks

Now, we can't help but wonder if today's mustached men like Brad Pitt and George Clooney are paying homage to those manly men of the '70s like Burt Reynolds, Tom Selleck, and even the Marlboro Man. Whatever the reason, we find ourselves asking the age-old question -- are mustaches on men a fashion do, or a fashion don't? You decide.
