If your office is so cold that you can't click a mouse button properly, it's time to get a new job. If that isn't a viable option, just buy a heated sleeping bag for your hand that's shaped like a dolphin and also happens to be a mouse pad. Yes, straight from the craziest part of Japan comes perhaps the strangest mouse pad we've ever seen. You actually keep your hand inside the dolphin's mouth, and his warm innards keeps your mousing hand nice and warm. I guess you need to provide your own mitten for your other hand to keep things balanced. If nothing else it'll send a message to your boss that his extreme cheapness when it comes to the heating bill is driving his employees to the brink of total insanity.
