This brought to mind a video that was doing the rounds of robotics labs in the mid 90s (I happened to be adjacent to one at the time).
Some researchers were demoing their latest elegant software upgrade for their experimental robot (large, solid, clunky) for the company execs. It was supposed to retrieve a bottle of beer from the fridge. It had done the job perfectly in trials of course, but with the extra attention it decided, for reasons never made clear, to go route one. With calm deliberation, it punched its arm straight through the fridge door, grabbed a beer bottle, retrieved it, and to the consternation of the assembled onlookers, swung round, pulling the fridge door off its hinges in the process.
(You had to be there - just had a look online, but can't seem to find it. I've probably remembered it wrong.)
