Orel Hershiser's improbable turn to a possessed madman

ESPN's Sunday Night Baseball was already off the charts tonight with their new 'bathroom stall' camera feature, but the stunning presence of a completely insane Orel Hershiser, proud new owner of the greatest Joker portrayal to date, simply stole the show. 

Did John Miller forget to wear pants?  Did Steve Phillips suddenly go back to his part-in-the-middle look when the camera panned away?  Did Elaine give him the Uncle Leo treatment and paint angry eyebrows on his face?  Whatever it is, this normally mild-mannered individual wants to kick the living shit out of everyone.

At this point Hershiser has the entire nation mentally crippled in a highly uncomfortable and paranoid state, yet John Miller thinks the guy is an absolute ray of light, like he's making god damn balloon animals and handing out cotton fuckin' candy. 

What happened to this dude?  If an alien tears out of his stomach and hops on Miller's head to act as an unflattering toupee, we won't exactly be surprised.
