#5 Sid Vicious would like a retake, Mr. Jim Ross

Sid Eudy, better known to the world variously as Lord Humongous, Sid Justice, and most of all Sid Vicious (no relation to the punk singer) has had a storied career where he has operated at or near the main event level.
He was considered main event talent in the NWA and later WCW, where he joined the fabled Four Horsemen faction and challenged Sting for the World Heavyweight championship.
Sid, was likewise considered the main event draw in WWE, where he feuded with men like Shawn Michaels.
However, there is a moment Sid would rather forget about during his WWE run. During the 1990s most WWE pay per views did not have individual names save the big one (Wrestlemania and Summerslam) but were referred to as In Your House.
It was during the pre-show, which was airing live on cable, that Sid made a bit of a flub and asked for a do-over. You can watch in on this link--but Sid would probably prefer you didn't!
