Christmas traditions on your Wiki? Or any other holiday related traditions?

On the German language Wikipedia, there is a tradition of creating an article wishlist a while before Christmas and some angel like Wikipedians will have a look over it and decide which articles they are gonna gift other Wikipedians with. The articles are created as subpages of the wishlist page and moved to the namespace by one editor who has agreed to be this year’s “Christkind” on December 24th. A lot of the wishes on this list are somehow related to Christmas, e.g. Christmas songs or movies, but there are also wishes for articles on unrelated topics, like sportspeople, monuments or animals. Only a few wishes actually get fulfilled each year, but I somehow like this tradition - although this year I did not participate, shame on me!

Does your wiki have a similar tradition, either on Christmas, or for any other holidays?
