The rules of the Royal Rumble match are that elimination occurs by leaving the ring over the top rope and onto the floor. Randy Savage forgot this when he exited the ring by jumping over the top rope to chase his on-screen nemesis Jake Roberts down the aisle. Savage's scripted elimination was to take place later in the match as part of the final four remaining wrestlers. However, he was let back into the ring, with the announcers covering for him by saying that a wrestler had to be thrown over the top rope by another wrestler in order to be eliminated from the match.
Later showings of this event edited out the cheering for Hulk Hogan's elimination, however you can still see the people jumping up to cheer his exit.
Announcer Gorilla Monsoon said Ted DiBiase was in the Royal Rumble match the year before but he wasn't, he was in a Tag Team Match with Virgil against Dustin & Dusty Rhodes.
