My Boys marathon (12:30pm, TBS) - In advance of the Season 4 premiere (tomorrow night), TBS is showing a marathon of the best episodes of their original comedy series, "My Boys." Today's 3-hour marathon features some of the best episodes of Season 3.
Dogs vs. Cats (8pm, Animal Planet) - A debate as old as time itself: which species is better, dogs or cats? I know where I come down (meow). I'm betting in the end they won't actually pick a side, but should be a fun show.

Being Human (10pm, BBC America) - Season 2 opens with the vampire society in complete disarray after Herrick's death, and George feels like a changed man after killing him. That is, until he discovers a horrible truth about Nina.
