In professional wrestling, a stable is a group of wrestlers within a promotion who have a common element -- friendships, either real or storyline, a common manager, or a common storyline -- which puts them together as a unit. Stables can be small alliances of three to six wrestlers (like Evolution, The Cabinet, MNM, The Dudley Boyz, Team Canada, Planet Jarrett and others), or supergroups that include up to half the promotion's talent roster (like the New World Order (nWo) and Sports Entertainment Xtreme). Often the loudest of them appears in promos, occasionally with another wrestler whose gimmick is to be largely silent, perhaps even mute, but nonetheless nodding or gesturing in wild agreement.
