A 2011 short film about Roosevelt's moving the day of Thanksgiving

Happy day after Thanksgiving! Hope you're thankful for the day, as that comes from 1941, when President Roosevelt used an executive order to make Thanksgiving the fourth Thursday in November.  This four and a half minute short looks (smirkingly) at the controversy of 1939, when Roosevelt made it a week earlier.  (Though, er, it wouldn't have made a difference this year.)  There are dancing Nazis.
