Merv Hughes was an Australian cricket pitcher who could throw a hell of a fast ball, and he also had a hell of a mustache. He knew how to brand himself, which is pretty outstanding considering I don't know how many other people in the cricket world are worrying about that part of their career. That's the thing about sports. You can suck, but if you have a cool thing about you then the fans will still show up.
I find the concept of insuring your mustache to be a little tenuous. Hair seems so much less permanent than something like your legs. Take for example the fact that hair just falls out. Legs do not. Your whole mustache could be ruined with one stray shaving accident or a quick burst of flames in your face.
