5 of the greatest OMG moments in WrestleMania history

With WrestleMania 33 taking place Sunday, theScore is celebrating the WWE's annual marquee event throughout the week. Here, we look back at the history of the Showcase of the Immortals and single out five moments that made our jaws collectively drop to the floor.

Hulk Hogan slams Andre the Giant, WrestleMania 3

It was the irresistible force meeting the immovable object. A clash of the titans. Two juggernauts coming to blows in a colossal battle of epic proportions.

Only Michigan's Pontiac Silverdome could hold a match of this magnitude, with Hulk Hogan defending his WWF Championship against the undefeated, 7-foot-4, 520-pound Andre the Giant.

Slamming Andre seemed cool in theory, but felt like an insurmountable task for any human being to actually pull off. Even taking the big man off of his feet at the time warranted a badge of honor, considering his reign of dominance over such a long period of time. Hogan, the ultimate fan favorite, entered the show as a clear underdog, making the end result all the more miraculous.

Yes, the Hulkster did the impossible by lifting Andre off of his feet and throwing him down on the canvas. It was the WrestleMania moment everyone desired to see, but very few thought was realistic. It also lit the fuse to the phenomenon we'd all come to know as Hulkamania, and the rest - as they say - is history.

Edge spears Jeff Hardy, WrestleMania X-7

Tables, Ladders, and Chairs II at WrestleMania X-7 was chock-full of crazy, breathtaking spots, with arguably the three greatest tandems of all time in The Hardy Boyz, Edge and Christian, and The Dudleyz putting forth another instant classic with the aforementioned tools of war.

Jeff Hardy had the ladder slightly out of position, making grabbing the tag team titles hanging above the ring more of a chore than it had to be. The ladder even moved out from underneath him ever so briefly, leaving Hardy dangling 15 feet in the air with only the mat below there to break his fall.

Bubba Ray Dudley regained his composure to dispose of Hardy's ladder, while Edge climbed another painter's ladder that was erected in the corner. This was the setup to what would not only be the highlight of the match, but a moment that WWE would utilize as part of the opening for its weekly programming for many, many years.

Edge spearing Jeff in midair forever defines TLC II, and accentuated how far those six were willing to go at a time when the audience was bloodthirsty for that level of danger. They continuously pushed the envelope, and thrived on one-upping each other. It was a fun yet precarious game of who could outdo who.

Brock Lesnar botches Shooting Star Press, WrestleMania 19

Brock Lesnar had successfully performed the shooting star press - a maneuver where the wrestler jumps forward from an elevated position while executing a backflip, landing on the opponent with a splash - several times before, although most came during his time training in Ohio Valley Wrestling or during the occasional dark match prior to making his television debut.

The original finish of his WWE Championship bout at WrestleMania 19 against Kurt Angle was Lesnar bringing the high-risk flip out of retirement to pin the Olympian and capture the gold in Seattle. In his autobiography, "Death Clutch," Lesnar wrote that his boot slipped off the top rope, resulting in him under-rotating and coming down awkwardly on his neck, giving him a concussion.

Thinking on the fly, Angle rolled over to cover "The Beast Incarnate" for a count of two. He then picked up a visibly dazed and loopy Lesnar, who caught him out of nowhere with a third F-5 finisher for the pinfall victory.

More than a decade later in an appearance on Steve Austin's podcast, Lesnar revealed that he was talked into doing the press by backstage agents and officials, and that he should have put his foot down, been more selfish, and refused to do it.

Edge spears Mick Foley through a flaming table, WrestleMania 22

Mick Foley's career was devoid of a signature WrestleMania moment prior to squaring off with the Rated-R Superstar at Allstate Arena. The Hardcore Legend had a poor showing at WrestleMania 2000 in the Fatal 4-Way main event, and wasn't in top form when he teamed with The Rock against Evolution at WrestleMania 20.

In this environment, Foley was free to create a violent masterpiece with someone he had a lot of respect and admiration for in Edge, who was starting to gain a ton of momentum as a heel character. The two used barbed wire, thumb tacks, tables, and chairs to tell their story, stealing the show in a hellacious battle that evoked memories of the old Extreme Championship Wrestling.

In what would end up being his final WrestleMania match, Foley literally went out in a blaze of glory after Edge speared him through the middle rope into a ringside table that was lit on fire by Edge's now-former girlfriend, Lita. The flames were so intense that they even scorched off Foley's forearm air.

The waiting game was over, as Foley had finally left his footprint in WrestleMania lore, proving that there's just as much to be gained in defeat as there is in victory.

Shane McMahon dives off Hell in a Cell, WrestleMania 32

Shane McMahon makes his (here comes the) money in the squared circle - on the rare instances he's actually competing, mind you - by being a daredevil, performing spots that very few would even consider trying. He'll never be confused for a master ring technician, so to compensate for that, the son of company chairman Vince McMahon puts his body on the line in creative ways to make an impact, both literally and figuratively.

WrestleMania 32 in Dallas marked his first match for WWE in roughly seven years, and with the Hell in a Cell stipulation to work with, it was a foregone conclusion that he would be leaping off the top of the 20-foot structure at some point against The Undertaker. Frankly, it was the only thing left for McMahon to jump off of that he hadn't before.

With 'Taker's prone body lying atop the announce table, Shane-O-Mac scaled the side of the cell, prayed to the heavens above, and took his death-defying plunge in front of over 100,000 fans ... only to crash and burn in spectacular fashion.

Shane was fine, though, giving the audience a thumbs up as he was stretchered back up the entrance ramp following his loss.
