I have an old thinkpad that's survived a decade and a half and been retired to siting alone next to some speakers and sometimes playing music. Well tonight, completely out of the blue, I found the whole thing COVERED in a solid black layer of ants.

Sure, there's probably a couple ancient crumbs under the keyboard but like WTF? There are ants nowhere else in the house. Did they try to form a colony in the laptop because it was warm?
