Cena was a guest referee for a match between what was supposed to be a 4-on-4 tag team match between CM Punk's Nexus and Barrett's new team, "the Corre", with the stipulation that the losing team would not participate in the Royal Rumble. Cena then proceeds to throw both teams out of the match leaving just Punk and Barrett, attack both of them before the match starts (knowing they can't retaliate or else they're DQ'ed), throws Punk out of the ring, leaves the ring to sign autographs while Barrett covers Punk, and finally disqualifies both competitors while they're on the canvas... for using excessive profanity.
John Cena: "The reason for an announcement so big, is that because over the past month, the WWE has been turned upside down. It's been like a... like a rotten episode of Star Wars. *beat* Allow me to enlighten you: A short time ago, in a WWE universe not so far away, the evil emperor John Laurinaitis convinced the world's largest Jedi to join the dark side and become Show Vader. Show Vader then channelled his new-found anger to wage war against the younger, more handsome Jedi John Cenawalker. The two did battle in an epic fight so big it had to be contained in a fifteen-foot-high Death Star. With the evil emperor sitting at ringside, but not to be outdone and to be sure the match was fair, the old, decrepit, dust-covered Jedi Yoda McMahon sat there next to him. The entire galaxy was involved: Jabba the Funkasaurus, Han Soul-bro, Bro-bacca the woo-woo-wookie. Hell, even R2-A-ri and Santin-3PO were there. The battle was so vicious, that Show Vader had Cenawalker in a corner, and breathing heavy as he most often does, said *wooosh* *wooosh*'I am your father!'. And to be quite honest, that totally weirded me out, because I know my dad and my dad's not Show. So I climbed out of the Death Star as quick as I could, using a maneuver that was easier than bagging womp rats back in Beggar's Canyon, and when I hit the floor, the ancient, old Jedi Yoda Mcmahon leaped out of his chair and said to the face of the evil emperor, 'No chance in Hell have you.' *beat*'Fired you are!'
Chris Benoit locks Paul Heyman in the Sharpshooter while Cena makes Pauley eat soap. See it here. John was having a lot of fun telling Benoit when to apply pressure with the submission and when to ease up so Heyman could do something other than scream and tap out.
"Eff me? Eff moi? I believe that the correct verbage is F.U, Paul Heyman!"
Maybe funnier for one that doesn't like Cena, but there was a slapstick-like moment of the borderline- Epic Fail variety in his most recent match against CM Punk. Cena sets up for his shoulder tackles - the first of his Five Moves of Doom. When he makes the return pass for the second, though, Punk hits the deck, causing Cena to come up empty and fly halfway across the ring before spilling out onto the floor.
Probably made even funnier by his obvious "YOLO!" look toward the ref right before he does it.
This moment. It starts off with Cena slamming Edge, then Cena has a spaz attack when doing the Five Knuckle Shuffle, then Big Show chokeslams Edge, then Edge gets gets pinned by four wrestlers. Everything about this is funny.
This moment in 2011 Cena tells The Miz and R-Truth that his tag partner for Survivor Series is The Rock, And when he says that he spits on the mic.
Raw on 4/8/13. Cena came to the ring after Beating The Rock for the WWE Championship at WrestleMania 29. And he basically messed with the crowd for the most part in this promo, But the funniest part was four minutes in the video Cena said he may do a Championship dance, And then he did a embarrassing shake, Then a kick, But the funniest part was that Cena teased a heel turn.... By doing a HEEL turn!
May have turned into a "Funny Aneurysm" Moment for his fans because he came up with an injured achilles about a week later.
3/24/14: John Cena in the bathroom and in the mirror he see's Eric Rowan. When he looks back, Rowan's gone. Cena has a WTF Face.
The following week, as Bray is celebrating his win over R-Truth a strange figure appears dressed like Eric Rowan, sheep mask and all. It's Cena, but can you imagine Cena wearing that sheep mask over his face?
4/7/14: Cena enters and the crowd, more or less angry that he beat Bray the night before, decide to sing to his theme. What do they sing? "John Cena Sucks"....in time to his own theme song. This had happened before during a show at Peru but it was still mixed in with wild cheers and thus not as audible. This time it came out loud and clear.
