The 11th Doctor's Sonic Screwdrivers (currently series 5 and 6).
If you have no idea what I'm talking about, take a gander at the show Doctor Who on BBC America. It reruns at 4 and 5 (this is central time, so 5 and 6 eastern time) and is fantastic. New episodes start back up again on August 28th at 8pm (central time, 9 eastern time). Watch it, it's phenomenal!
