Sharing Day, Holiday Geekery Edition

You WILL have a merry Christmas!

With Christmas, Chanukah, and the Winter Solstice all happening right around this time, it's definitely the season for giving. So here's what I would like to know about you:

What is your favorite Geek Holiday memory (the best geeky gift you have ever either given or received, a cool geek-themed holiday gathering, etc.)?

In return, if you wish you can ask me any question you like about whatever you like, which I will answer either completely truthfully or not at all (in which case you can ask something else). You don't have to ask me anything if you don't want, but I'd still like to hear your answer to the question.

Speaking of which, my answer would be:

One year when I was a kid I got this big plastic Japanese robot called Mazinga that had a ship docked in its head and missiles that fired out of its hand. I had seen very little anime and didn't know who the heck Mazinga was, but he was cool. I had that thing forever and got a lot of enjoyment out of it.

Now it's your turn!
