Well...yeah, Vince getting stunnered is a landmark wrasslin' moment showing that NO ONE was off limits to the loose canon that is Stone Cold.
Since then authority figures getting beaten up is relatively standard practice, diminishing returns and all.
The only repeat of that kinda scenario that really left me shook was of course Kane tombstoning Linda McMahon on the stage, another classic Kane moment to put in the Kanetober list.
Meanwhile what are the other times Vince getting beaten up has been a notable moment in recent-ish memory? I'm thinking the Nexus but I swear there was another one that felt pretty surprising since then (and no, it's not da big dawg)
