I think Backlund may have had one for himself too. It was either by other wrestlers or some fans.
Don't remember which.
But yeah, last was Angle at Unforgiven 01, I believe.
It really only works on certain occassions. Unforgiven 01 it worked because they were all WWF wrestlers happy that Angle took the title away from the Alliance.
When Mankind was by DX on that fateful Raw, it made sense because they had sort of adopted Mankind as a friend.
The Bret Hart win at WrestleMania 10 parading made sense because the faces were 1)Happy for Bret to get the belt back he was screwed out of. And/or 2)They were glad that someone FINALLY dethroned the seemingly unstoppable champion Yokozuna.
Benoit being paraded at WrestleMania XX could have made sense if it was by a good majority of the people HHH had "buried" while champion, but since some of them had turned heel, it wouldn't work that way, hence the classier, IMO, cellebration.
