That’s it, he’s dead

An open-forum question:

What are your go-to examples of moves/bumps that looked so violent that you immediately went “that's it for him” when you saw it?  Despite the subject line, we should automatically exclude Mankind at King of the Ring 98 (maybe even those hardcore matches from
Japan, as well) or else everyone would reflexively say that.  Surely Dean Malenko DDT-ing Scotty Too Hotty off the top rope at Backlash 2000 has got to be at the top of a few lists.

First time I saw the Steiner Screwdriver.
