Ian Robertson has provided the following nugget:
At xmas every year for some 24 hours by far the busiest website in the world far is Norad Santa .

An uptodate activity (you need to register):
Santa is planning ahead for when humans colonise the rest of the Solar System – he may decide to move to another planet! In this fun activity pupils analyse planetary data to find which planet best satisfies Santa’s future requirements.

They then e-mail Santa to advise him of their decision, and – if you wish – design a Christmas card to show why this planet is such a great place to spend Christmas.
