Can we get sucked out of airplanes?

Not since living in Cheyenne and flying back and forth have I spent much time in a plane. There just hasn't been a need for it.
This article at Slate reminded me of a time I was on a flight coming into Denver late one night. I was in one of the seats toward the back of the plane, which didn't have that many people on it. All of the flight attendants were up toward the front and it was eerily quiet.
It was then that I looked at the rear door just a few feet away from me and wondered what would happen if there was some deranged guy in my seat who decided to pull the lever. Would we all get sucked out? Would the plane depressurize and go down? It was one of those "What would happen?" conversations you have with yourself.
