Could you imagine being stuck in a time loop, reliving the same day over and over?  Where you remember everything, and everyone around you remembers nothing?  This is exactly what happens to Phil Connors in the classic movie Groundhog Day.  While living without any consequences is fun at first, once Phil realizes he is stuck seemingly forever, things get pretty dark, pretty quick.  This week we take a look at this time loop, and figure out how exactly he got out, how long he was in the loop, and how he got stuck in the first place.  We will also discuss how long it takes to learn piano, master a foreign language, and plan the perfect petty robbery once you know exactly how the day will play out, down to the second.
