Odin guide my hand, and my DVR as the History Channel aired the Season 1 finale of Vikings. The ninth episode of the new series, ′All Change′, had plenty of competition for us TV fans. AMC′s ′Mad Men′ aired its episode centered on the assassination of Martin Luther King, Jr.. For you Dr. Who fans, BBC America aired its 4th installment in its 50th anniversary of our favorite Time Lord, featuring The Doctor portrayed by Tom ′The Scarf′ Baker. Tru TV ran two more new episodes of ′Hardcore Pawn′, which makes ′Pawn Stars′ look like ′Antique Road Show′ on Sominex. Naturally, for those of you who simply cannot get enough politics, the Fox News Channel aired a one-hour interview of George W. Bush by Dana Perino. Thank goodness for DVR technology so I could keep up with everything!
