This gross-out moment is a perfect ending because it combines several threads from previous moments, namely Vince McMahon, a sweaty orifice, Big Show, and butts. Only Vince McMahon's deranged mind could conceive of a running segment so disturbing as the "Kiss My Ass Club," which was exactly as it sounds, as McMahon would force WWE employees to kneel down, pucker up, and smooch McMahon's exposed cheeks. Each and every time Vince went to initiate a new member over the years has been worthy of this list, as Vince would bare his behind, make his butt "do tricks" and gross out the live audience and fans watching at home. Sometimes a victim would be spared or saved from actually having to join the club, though some, like William Regal and Jim Ross, had to do the unthinkable. Strangely, the most disgusting moment somewhat related to the Kiss My Ass Club came at the hands of DX to Vince McMahon himself. During a handicap cage match in 2006, Shawn Michaels and Triple H grabbed McMahon and shoved his entire face into the exposed and waiting canyon that is the Big Show's giant sweaty behind, a lasting image more than worthy to cap off this list. http://www.youtube.com/watch?v=MGfdD_VBuOk These 13 moments only begin to scratch the surface of gag-worthy moments, moves, and memories.
