Notes
Puxatornee and the events in this strange episode loosely resemble the bizarre events in the "time-travel" Bill Murray movie Groundhog Day where the same day happens over and over again only to be changed by Bill Murray in the town of Punxsutawney, Pennsylvania. The film takes place on Groundhog Day, another winter holiday. The character names are references to the film It's a Wonderful Life, which also takes place at Christmas. Characters in the film include Mr. Potter and the Bailey family; the film was directed by Frank Capra and starred James Stewart, Donna Reed and Thomas Mitchell, among others.
