Billy Ray Cyrus has the quintessential country music mullet. He wasn't the first singer to sport the hairdo when he released 'Achy Breaky Heart' in 1992, but the song's popularity made him the mullet poster child. Cyrus continues to show reverence to the Kentucky Waterfall, even bringing the look back for a short bit in recent years. His dedication to the hairstyle is almost enough to bring a tear to the eyes -- for better or worse.
