What's the most unusual or unexpected gift you've received that turned out to be incredibly useful?

I got CD from gaming magazine. There was games, software and most important Diskmags. Diskmags was basicaly offline sites built mostly on HTML and Flash. That had huge impact on me because as a kid i didnt have internet but i was curious how it works, so i learned how to make website before i was 12. Would be literally impossible without it coz we didnt have internet. Most of people didnt have internet back then in postsoviet countries...
