Twelve days to Christmas, Twelve days to Christmas;
Look at the way they do their Christmas shopping!
They can go shopping and still remain calm and sedate.
These are the people we envy and the people that we hate!

Nine days to Christmas, Nine days to Christmas;
Still enough time to do your Christmas shopping.
These are the people who plan their days wisely and well.
These are the people who shop in time, and they can go to…

Four days to Christmas, Four days to Christmas;
These are the folks who never waste a second.
Full of a chilly efficiency, loaded with gall,
Never too early and never late and they’re the worst of all!

One day to Christmas, One day to Christmas;
How will we ever do our Christmas shopping?
Why did we ever delay so long? Who can recall?
Some of the family may not get a Christmas gift at all!
