You too will be amazed as the Spirit Clausometer comes to life when the mug is filled with a hot beverage. CHRISTMAS CHEER: The back of this mug features the classic line from the movie Elf "The best way to spread Christmas cheer is singing loud for all to hear" which Buddy says to Jovie, the unenthusiastic Gimbels Department Store employee who doesn't like singing in front of a crowd. GREAT GIFT: Packaged in a full colour gift box the Elf Heat Change Mug makes the perfect present for fans of this classic American Christmas comedy movie. It is also a great Secret Santa gift for that hard-to-buy-for friend, family member or colleague.
