Wrestling Association of Championship Krushers, also known as W.A.C.K!, is a professional wrestling promotion for children that airs on Nickelodeon.
A mock press conference was aired on November 22, 2006 to unveil the W.A.C.K! promotion. The series debuted with a 3-hour block on November 25, 2006, which was hosted by stars, Devon Werkheiser and Lindsey Shaw, of the Nickelodeon TV show, Ned's Declassified School Survival Guide. It was originally supposed to air live every weekday, but it changed into a series of specials. The reason for this is not known. Although it was set to return in 2007, no new episodes of the show aired, as filming has been postponed for an indefinite period of time.
