1994 Altima - Brake lights always on? What's the deal?

My wife couldn't get her car to start this morning. A bit troublesome as we had recently had the alternator and battery replaced. We thought perhaps she didn't shut the door tight enough and/or left a light on inside the car.
After jumping the car, I noticed that the brake lights were on. The car (manual shift) was in neutral and the parking brake engaged. Even after disengaging the parking brake the lights were on solid (not that the parking brake should affect the rear brake lights, but I wanted to be sure). We finagled with the brake pedal as well thinking it might not be releasing fully, but it seems to be working fine. It's not getting caught on anything and is returning to the normal position.
I checked the fuse, and it appeared fine. I don't have any spare fuses to swap out and check with, unfortunately. They're usually pretty obvious when they're burned out, right? The middle arc-thing should be charred and broken - not the case here. When I removed the fuse, the lights did go out (but of course that means no lights when pressing the brake pedal.)
After letting the car run for a while to charge up the battery, we tried turning off the car - the brake lights were still on... so that was definitely the problem.
She was already late to work so I told her which fuse to remove when she gets to work so it (hopefully) doesn't kill the battery, then can put it back in when she leaves work. Driving with your brakelights always on certainly isn't optimal but driving without them working would be even worse.
So, does anyone have any idea what might cause the brake lights to stay on permanently, even when the car is turned off, and the fuse seems ok?
