In England, Merry means Blessed! Whoo hoo for fun facts! And in Australia, Santa Claus or Father Christmas, or whatever you call him, has kangaroos that teleport him instead of reindeer! No rudolf on his sleigh! Have a wonderful holiday season everyone, and a happy New Year! (2010!!!!!!)
Opps, sorry, forgot to say that a long time ago it originally meant 'Blessed'. Like hundreds of years ago. Eh, what do I know? You have a good holiday too! =)
