The film National Lampoons Christmas Vacation in 1989 featured some characters drinking Egg Nog out of glasses in the shape of Mooses (or Reindeer).  These were apparently modelled in the style of a character called 'Marty Moose' from 'Wally's World'.  No, we have no idea what this is either.  These mugs are now a cult classic and in very high demand. 

Canadian company 'CanadianMoose.com' can supply replicas of these mugs similar to the originals.  For more details please follow the link below:
