Calibrating Who is Doctor Xzibit?

On this week's Constantly Calibrating we ponder the rumors of Peter Capaldi only being on Doctor Who for one series, much like predecessor Christopher Eccleston. Who could possibly take over for him, should the BBC decide to go through with their rumored "radical change" for the long-running show. In addition we chat about World of Warcraft's next expansion Warlords of Draenor, thoughts on Arrow and its own rumor-mill, plus at the age of 29-years-old (nearly), I, Joshua Silverman, have learned to ride a bike!
