Ever stuck in a real life situation that called for an adventure game solution?

At my old school our science labs and computer rooms used to get locked before school and at break times, which meant if you were early to class (or more frequently if your teacher was late) you had to stand in the corridor waiting. Our form room was a lab and we often had to wait 15-20 minutes before we could go in for registration. I noticed that - presumably for fire safety reasons - if you pulled the handle of one of these locked doors from inside the lab the door would unlock. I also noted the half-centimetre gap between the door and door frame. At about this time we were doing a series of experiments in physics on the resistive properties of different lengths of wire...

I'd got my wire threaded through the gap and looped around the inner door handle when the lab technician walked past.
