saddest display of a wrestler past their prime

Ric Flair is my favorite wrestler of all time and to see him on Raw the last 3 weeks has been kind of depressing as they keep using him as a sad pathetic old man and it got me thinking what are other examples of seeing wrestlers past their prime that looks depressing, there's Greg Valentine actually wrestling a match in some dude's back yard and God knows how many big 80's stars that ended their careers in their 60's wrestling in front of 50 people in some no name towns.

Have you SEEN Heroes of Wrestling?!?
Anyway, Bruno was very vocal about not wanting to go out like that in the 80s while Vince was trying to squeeze a few last gates out of his name and he decided to leave and never return.  Which is another reason why Bruno is f------ awesome.
