The guy pictured above is Joshua Micheal McMahan. He died on April 18, 2012. I didn't know Joshua, and until yesterday wasn't even aware he had ever existed, but now I wish I knew him thanks to this amazing obituary in the Ponca City News:
Joshua Micheal (nope, not a typo it’s really spelled that way) McMahan left this world April 18, 2012. He was loved, hated, praised, and cursed by relatives and friends alike. He ultimately passed as a result of being stubborn, refusing to follow doctors’ (or anyone else for that matters) orders, and raising hell for a little more than three decades. He lived life on his own terms.
