What is your pick for the most underrated finishing move of all time?

I was just randomly thinking about this and everyone rightly talks about things like the Stunner, Burning Hammer, One Winged Angel but what finisher do you love that doesn't get the flowers that you think it should?

For me, it's Trevor Lee / Cameron Grimes' Cave In, it's a move that always looks devastating every single time that I've seen the Carolina Caveman hit it! it's a perfect finisher because it looks disgusting but it can be done from 'out of nowhere' and can be done to anyone of any size.
