If you were kidnapped and could bring along only one personal possession, what would you take?

Well given the situation, it depends on if I get to actually use the item or not. If I could, I would definitely bring the sidekick. Technically, I probably won't be able to use it long since I would have to charge the thing. Being kidnapped, I probably would be stuffed in some trunk, or maybe in an underground room with no windows, maybe at the bottom of a well and my only visitor is lotion in a bucket, or maybe I'll be in some run down abandoned adobe in the middle of the desert somewhere in Mexico being tortured to spill my secret obsession with muffins. I doubt I would have the time or the place to charge my sidekick. But hey, I can dream can't I?
