Dark Messiah: might and magic. There is an orc final boss that was realy giving me trouble. For those of you who don't know Dark Messiah: think of it as oblivion where the physics influence the npc's as well... and you can pick things up and throw them, or just kick an enemy into a trap or canyons.
However, with this particular boss, there where no obvious spikes or canyons for me to make light work quick of this guy. So, after trying to beat him numerous times 'oblivion style' (block, chop, block) and utterly failing, I tried to look around to see what I could use to get the odds on my side.
The only interactive object I found was a small rock, but I figured, what the heck. Picked it up, threw it at the boss, and, in spite of what you would think, the muscular, 140 or so kilogram orc fell like I just threw a anvil at him. At this point, all I had to do was stand over him and repeatedly stab him with my daggers, since that attack would throw him back to the ground.
So, that's how half an hour of trying and failing finally went down in an all not-so-epic 30 second battle, thanks to the world heaviest small rock.
