The "NXT Riot". Bar none, the most frightening, awesome, and truly shocking moment in recent WWE history. Check the Raw section on the Moment of Awesome page for all the details.
During a 5-on-1 handicap match against the Big Show, all five members applied a submission move on the Big Show (Wade applied a leglock chokehold while the others applied kneebars and armbars to all his limbs) and choked him out.
During the Royal Rumble 2011, with the exception of Husky Harris whom was eliminated number 15, every elimination from number 6-18 were eliminated from a member, or members of The Nexus.
Wade Barrett winning the Intercontinental title from Kofi Kingston, by catching Kofi as he tried for the Trouble In Paradise & hitting him with the Wasteland, becoming the first Nexus or Corre member to bring singles gold to either group.
To clarify, Kofi was jumping/spinning in mid-air and Wade catches him cleaning on his shoulders in a fireman's carry. No adjustment necessary for then performing Wasteland.
