Undertaker and Kane get one for this. (As an explanation: in the weeks prior to No Mercy, Undertaker had been assaulted, been accused of infidelity, and had his hand broken by Brock Lesnar, and Kane had to deal with the Katie Vick situation.)
During Kane's hunt for the person who had put The Undertaker into a "vegetative state", Jack Swagger was giving a promo where he sang the Boomer Soomer song (complete with bouncing Jack Swagger head to show people which lyric to sing). Kane appeared half way through the song and Swagger slowly deflated before stopping entirely as Kane screamed "WAS IT YOU??!" Into his ear. Considering how straight faced The Undertaker angle had been played up to that point, it was an amusing break to say the least.
The Brothers of Destruction's first match tag-teaming in five years, from the 11.03.06 Smack!Down, against MVP and Kennedy. If you're not peeing yourself laughing at JBL's commentary (and blatant marking-out), Kane and Taker's "Who does the better scoop slam?" contest might get you, as well as the Brothers breaking kayfabe to chat at the end.
An even better moment is near the end of the match; Undertaker has hit MVP with Snake Eyes and Kennedy has been hit with a boot by Kane. Kane's response? He's just shrugging his shoulders and then leaves the ring so Taker finishes the match. Or we can't forget them rushing toward the two in a back and forth to "One-up" each other.
12-26-11. In the middle of preaching to John Cena to embrace his hate, this big red demon started a "CENA SUCKS" chant.
The week prior, during Kane's second assault on Cena, a woman in the front row can be clearly heard chanting "Let's go Cena!", while a man can be clearly heard screaming "CHOKE SLAM HIM, KANE!" A hilarious demonstration of Cena's divided audience.
During the RAW 15th anniversary special, Kane has met up with Lita. At first, you think there's gonna be some big fight and Kane mad about Lita marrying Edge, right? Nope. They're actually talking as in "So, how's the weather?" and "Seen any good movies, lately?" kind of talk.
Even better? Ron Simmons arrives and actually notices how awkward the whole thing is. One word: "DAMN!"
During the triple threat title match at No Way Out, CM Punk had set up Daniel Bryan for a superplex. Kane pulled him down off the turnbuckle and tried to superplex Bryan himself. CM Punk then pulls him down and goes back to trying to superplex Bryan. Kane then pulls Punk down again, inadvertently pulling down his shorts and exposing his ass to half the arena in doing so.
7/3/2012. At the start of the Super Smackdown Live!, during July 4th celebrations, Santino is having trouble lighting the BBQ for the roster. In comes Kane who just stares at the BBQ for a moment before doing the summon fire and brimstone part of his gimmick to light the BBQ. And the he just silently walks away as the crowd goes wild.
