#4 The Katie Vick angle

This moment in wrestling history is so shocking, even WWE won't replay it except in heavily edited formats. And with very good reason, considering it features some very non-family friendly element.
Kane was originally a silent red monster, doing the bidding of his 'father' Paul Bearer without pity or remorse. The wrestling kayfabe reason for Kane's silence was that his throat had been damaged in the fire set by his 'brother' the Undertaker when they were children.
Kane was also supposedly horribly scarred from this event, hence the mask to cover his face.
During a feud between Kane and Triple H, The Game decided to utilize his mastery of mind games against his much larger opponent. When Kane kayfabe attended the funeral of an old girlfriend, Triple H seized upon the opportunity.
He proposed to show a video of Kane at his ex-girlfriend's funeral. In the video, Triple H wearing a Kane mask proceeded towards the coffin and what happened next was something wrestling did not expect to see. The scene revolted even the jaded Attitude Era audience, and is widely regarded as one of the biggest gaffes the WWE has ever engaged in.
