I used to work with a DBA who was a pretty good lock pick. We had a server down on a saturday and neither of us had keys or direct access to the server room. We had been waiting about 20 minutes for the server guys to arrive when he started to pick the lock with a pick set. 20 minutes later he still wasn't in and was complaining about the complexity of the lock when our mutal friend who was an engineer came and helped. He grabbed a chair, opened the roof tiles, peered in to the room asked for a broom then opened the door by pushing the handle down on the inside of the server room with the broom from the ceiling. It took him less then 30 seconds. By the time the server guys showed up we were long gone and they were scratching their heads to how the server came back up.
