In Adam "Edge" Copeland's autobiography, On Edge, there is a picture captioned, "One of the best ways of getting heat from the crowd is to spear Lita". A year or so later, his affair with Lita was exposed... yeah, he did get a lot of heat for "spearing" her (Lita got more, though).
Also in the same vein, in 2003 WWE tried an all-Divas trading card set: WWE- Divine Divas. Card number 82 in this set: "Double Trouble- Lita & Edge."
All Lita stuff aside, towards the end of Edge's book, he said that he thinks he's headed for a heel turn, and states that while he's okay with that, he works better as a face. In the best way possible, he was wrong.
At "his hair vs hair" match with Kurt Angle at Judgment Day 2002, Jerry Lawler said Come JR, admit it, this guy needs a haircut when Edge was coming out and would later win the match. Just forward to 2012 where Edge got what else after retiring from wrestling… a haircut.
During Jeff Hardy's first stint in TNA, his entrance video contained the words "See You In The Future." Fast forward years later, and Jeff is now back in TNA.
During the annual WWE show in Iraq in 2003, "Stone Cold" Steve Austin actually gave John Cena the Stone Cold Stunner after being unimpressed with his "You Can't See Me" taunt. This was before Cena was made the top face of the company as Austin had been in the late '90s; the event has become both funnier and much more symbolic in hindsight.
Edge seems to get a lot of these as he cut a promo shortly after winning the 2001 King of the Ring where he took down Billy Gunn, claiming he failed to get over after he won the 1999 KOTR and went on to say "If in two years I'm not WWF Champion you can just shoot me because I promise not to 'Billy Gunn' this account". In two years, Edge would get a broken neck and be out of action for over a year and would struggle as a babyface before being turned heel and get paired with Vickie Guerrero in a storyline and although he became WWE Champion several times he never won it cleanly. To top that when he returned in 2010 as a face he effectively bombed and the crowd turned on him at his WrestleMania 26 match with Chris Jericho thus forcing the creative team to turn him heel again. Fate doesn't like to be tempted, Mr. Copeland.
And speaking of which, at the end of Edge's book, he said he worked better as a face than a heel. From 2004 onward, we discovered that he was wrong.
Pete Rose appeared at WrestleMania XIV, XV, and 2000 (a.k.a. XVI) and was beaten up by Kane at the first two events (he was given a stinkface in the third). In his first appearance, which was held in Boston, he insulted the Boston Red Sox (whom his team, the Cincinnati Reds, had beat in 1975 to win the World Series) and said the Red Sox couldn't win a World Series and mocked the Curse of the Bambino (before Kane came out and destroyed him to cheering from the crowd). Two World Series wins for Boston later, who's laughing now, Pete?
And the nickname of the Cincinnati Reds in the 1970s was the Big Red Machine, which became Kane's nickname in his first run.
Triple H vs. Ultimate Warrior at WrestleMania XII, Currently, Triple H is one of the main eventers in the WWE and in order to kick out of the Pedigree, Triple H's finisher, you need written permission from Triple H. During this match, Triple H used the Pedigree on the Ultimate Warrior and Warrior just stands up from it like it's nothing. If this were to happen in the current WWE, the career of the wrestler would possibly be on life support.
That's also cause Warrior has a tendency to No Sell opponents' offense, especially their finishers.
Also, Triple H was the low man on the Clique totem pole. Warrior was coming back after a 3+ year-long absence and Vince needed someone to sacrifice to him.
Again concerning Triple H, the end of an old theme song of his finished with the snarky remark, "Who's sleeping with who around here?" Guess who married the boss'sdaughter.
And don't forget that they were married in kayfabe before they were married in real life.
Deliberate homage, "The Game" is wrestling, Ric's bragging about being the biggest cheater, and Trips (who is a gigantic Flair mark) talked about how people said they were students of "The Game" but he was "The Game".
On the edition of SmackDown prior to the 2009 edition of Bragging RightsJohn Morrison had a confrontation with his former partner The Miz, mocking RAW and its recent parade of guest hosts, by saying it had become a "poor man's Saturday Night Live" and asking "who's next, Big Bird?". Fast forward two years and The Muppets hosted RAW on Halloween.
Which contained another hilarious hindsight moment; Edge had at one point called Sheamus Beaker. So come the Muppets hosting, Beaker and Sheamus meet backstage, who tells Beaker he can't make it to the family reunion.
In a backstage segment with Trish Stratus, Melina said if she beat her "wouldn't that be a kick in the head?". I think this◊ needs no explanation.
Just before WWE Tough Enough season 5 premiered, contestant Ariane Andrew said in her promo "I am the next WWE Diva". She would be eliminated on the very first episode but then it became even more hilarious when she was signed anyway and also became the first of the contestants to debut on WWE TV in a regular role and make it to WrestleMania.
It becomes even funnier when, as of mid-2012, WWE actually released Andy Leavine, who did win that season.
Earl Hebner was the brother of WWF referee Dave Hebner, and a referee himself. He made his WWF debut at a 1988 card called The Main Event, (kayfabe) posing as his brother and screwing Hulk Hogan out of the title by counting three when his shoulders were clearly off the mat. Fast forward nine years...
Remember the Zodiac? Well, his catchphrase was "YES! NO! YES! NO! YES! NO!" Fast forward 17 years, and Daniel Bryan would use both "YES! YES! YES!" and "NO! NO! NO!" as catchphrases.
Ray Traylor, best known as the Big Bossman, was a prison guard who became a professional wrestler. His tag team partner Akeem, real name George Gray and better known as The One Man Gang, is a pro wrestler who became a prison guard.
New Japan Pro Wrestling's Antonio Inoki once defeated Pakistani Champion Akram Pehalawan in Pakistan to the surprise of the crowd. After the match, Inoki stood up and raised his fists in the air in a traditional victory pose. Possibly without realizing it, Inoki may have saved his own life by doing that, since the fans were originally going to riot in protest, but Inoki's pose made them think that he was actually praying to Allah. As of 1990, although it wasn't revealed until 2012, Inoki actually would pray to Allah on a regular basis, since he in fact converted to Islam.
At one point in their 'relationship', AJ Lee proposed to CM Punk, who eventually answered by telling her that he wouldn't marry her. In real life, they're now engaged, and got married in 2014, a mere two years after that very storyline.
Another one for Punk. In the 2010 Royal Rumble he ended up getting beaten up by Beth Phoenix. Roughly a year later the two would end up dating off screen. Depending on your humour, this could become even more hilarious now that they've since split up - and Punk's fiancée AJ was the one that 'retired' Beth from WWE.
Before her Survivor Series match against the Total Divas cast AJ cut a promo with her team trying to rally them up. Her specific words "Total Divas has new episodes playing on the E! Network...and none of you are on them. Total Divas doesn't want any of you". This team included Summer Rae and Rosa Mendes who would later be added to the Total Divas cast. Additionally Alicia Fox was on the team too and would be featured fairly regularly on a handful of episodes (though not as a main cast member).
