How much more paganism and mysticism can they cram into a song?

Chestnuts roasting on an open fire
Jack Frost nipping at your nose
Yuletide carols being sung by a choir
And folks dressed up like Eskimos
Everybody knows a turkey and some mistletoe
Help to make the season bright
Tiny tots with their eyes all aglow
Will find it hard to sleep tonight
They know that Santa's on his way
He's loaded lots of toys and goodies on his sleigh
And every mother's child is gonna spy
To see if reindeers really know how to fly
