Well, let's take a hypothetical more nearly realistic where I live. I'm in a one-story office building surrounded by a parking lot. My office is on the outside wall, and the one window in my office cannot be opened. There is an earthquake, and as as a result of the quake, the interior walls have sprung off-center, and my office door won't open. It's jammed shut with me in the office. No phones. No power. No one comes to rescue me. I throw my office chair at the window, and the chair bounces off. I look around the office. The ceiling is acoustical tile, but it's nine feet high, and my office furniture is that flimsy crap that hooks onto the wall so I can't stand on it or climb it to reach the ceiling so that I could climb out into the interior of the building through the ceiling. I'm not sure I'd want to, but I can't. I look around the office again. "Where's my Biel tool?" I cry.

The smell of gas wafts into the room.
