#2 Mick Foley (2004)
The 21st entrant in the 2004 Royal Rumble was originally supposed to be Test. However, he was found unconscious backstage by “Stone Cold” Steve Austin, the Raw General Manager, and he was replaced by Mick Foley.
Foley immediately targeted – and eliminated – Randy Orton, who had been in the match for 33 minutes. In doing so, Foley also eliminated himself before continuing to attack Orton on the outside of the ring.
