Well. Sort of working. Depends on whether you consider a fan that turns at 80rpm to be working. Or if you would consider my bike's brakes to be working (they'll make it stop, eventually, but they make a lot of noise and aren't any good for stopping short anymore; I'll probably end up hurting myself fairly soon).
Edit: I was going to say, doesn't that happen in aphasias sometimes? And Wikipedia says yes. Yeah, it's interesting how that happens.
