X-Com is great. I managed to get a hold of a copy that runs on my Windows Mobile phone. Not 100% the same, there are a few changes to it, but still, same overall impact. Still play it on my old PC as well. Still, NOTHING beats landing at a terror site, then realizing 2 turns in you're up against a pack of ethereals.....*shudder*

Really depends what you define as "work"

Pumpkin Smashing. Not that I do it, but I do see a lot of smashed pumpkins up to, and after Halloween.
