The MZone's running their own mustache taxonomy program over on their site, identifying and classifying a particular, slightly droopy philtrum-covering caesura as the "Buckstache." Looks eerily like a Sam Elliottish "Nevada Prospector" to us with a little color, but if you've got the photos to prove it, we'll endorse the new classification.
We wouldn't want to turn this into the kind of classification fracas inflaming the ranks of dedicated botanists, who've been known to come close to fisticuffs when discussing just what the hell an orchid is, anyway. We would like to say, though, that the 'stache on this guy:
...is a nearly dead perfect solid approximation of "The Cowher," perhaps with a little bit of the "Uncle Rico" mixed in for accent.
