Amazon has the new seasons of Dr Who on deep discount for today only. If you're a Who fan, I also suggest trying out the vintage Dr. Who from their Video On Demand service. The first season is one of the funniest things I've seen in years, since the BBC was on a tight budget back then. If you enjoyed Tom Baker using a tire pressure gauge as a "sonic screwdriver", you'll love the Aztec warriors inexplicably dressed in quilted jerkins that were presumably left over from some production of Robin Hood. The Aztecs are also masters of my favorite signature Star Trek fighting move: clasping your hands over your head and arcing them down onto someone's backs, which is apparently devastatingly effective in both the past and the future.
