As anyone with a passing interest in facial hair can tell you, John Oates' mustache is legend. So much so that Oates was included in the inaugural class of the Mustache Hall of Fame this month, cementing his spot as a mustachioed icon in the proud pantheon of hairy celebrities.

The Mustache Hall of Fame was recently established by the American Mustache Institute and Wahl Trimmers and hopes to "canonize the superior attractiveness" of sporting facial hair. Oates' fellow inductees include Dr. Martin Luther King, Tom Selleck, Teddy Roosevelt, and Salvador Dali.

And, really, you can't blame them for Oates' inclusion. Just look at that thing:

A maneater, indeed — and the attraction hasn't faded much since the 1980s. People still love Oates' mustache so much that these days it even has its own Facebook fan page and a short-lived cartoon series from 2009 where Dave Attell plays the mustache's voice.

Sadly, though, nothing lasts forever. Oates actually removed his trademark 'stache back in the 1990s, following the massive success of Hall & Oates. However, now he does sport a goatee, which he told Yahoo last year is "just facial hair."

"The mustache represented the old John," he said last year. "I didn't want to be that guy anymore, so I shaved it off. It was ritualistic in a way."

And while the mustache is gone, Hall & Oates remains. In fact, the duo is set to play the Giant Center in Hershey on May 4, followed by a stop at Allentown's PPL Center on May 6.

The Mustache Hall of Fame, for its part, is currently seeking to develop a physical location in Pittsburgh, according to AL.com. So, for now, you'll just have to ogle that 'stache like we've always done: from the safety of a screen.
