Join us as we ease you out of Valentine's Day and into half-priced chocolate day. David starts us off this week talking about a subset of Vikings that may have actually been horny, before Chris talks about why giving British tanks tea-makers gave tank operators a protection boost that tanks alone just couldn't provide. After half-time, David talks about what exactly "sentinel chickens" protect, and what they are (and no, unfortunately it does not involve chickens in flak vests and guns). Chris wraps it up by talking about the hottest and coldest temperatures on earth as well as some very aptly named locations. Also, Puppy Bowl.
