Once, I played a flind gnoll ranger who killed a goblin guard by throwing another (deceased) goblin into him. We (my bugbear partner and I) were trying to bluff our way into an underground goblin town by claiming the dead goblin I had slung over my shoulder needed healing. The guard didn't fall for it, but he fell when I threw his deceased brethren at his head and crushed his skull.
This doesn't help at all as far as rules go. I just like telling that story.
