I'll outline a situation that happened at work a while ago.
One co-worker decided to choke out another one, as a bit of a joke. He waited until his victim walked past, then leapt onto his back and applied a rear naked choke. The 'victim' flipped the attacker over, dropped him on the ground and choked him out himself. There was perhaps ten seconds between the 'attacker' initiating the attack and him waking up on the floor.
In that situation, the throw was both useful, and entertaining. It also demonstrates that not all SD situations will be life-and-death confrontations, and that bouncers have slightly skewed ideas of what is a suitable workplace prank.
