#2 WrestleMania XXVII
Helmsley walked into the Georgia Dome to battle The Undertaker dressed as an ancient king, flanked by an army of shield-bearing soldiers, as Metallica's 'For Whom the Bell Tolls' replaced his usual Motorhead entrance theme.
It was perhaps a jab at Undertaker's signature tolling bells, or perhaps just Helmsley using his influence to get his other favorite band involved in wrestling's biggest show, the booming pyro and sweeping lights in time with the song create a great effect.
Though it's the best part of the entrance, WWE's on-again-off-again relationship with Metallica, and the foursome's often-steep licensing fees, means that video releases and WWE Network streams of the event replace it with a sound-alike, which keeps many fans from experiencing this one in all its glory.
Becky Lynch has been challenged HERE.
