#4 - The infamous Katie Vick storyline
Triple H and Kane were involved in one of the worst storylines ever in the history of WWE. The Katie Vick storyline is easily something that comes to the minds of the WWE Universe when people talk about 'WWE going too far'.
While everyone knows that happened in the storyline, it is a shock to learn that the peak of the feud was actually shot in a funeral home. The segment which involved Triple H mimicking Kane and working with a corpse was actually shot in a funeral home and not a studio.
WWE then released a statement stating that it was just shot to make Triple H a more antagonizing character. The WWE Chairman was the driving force behind this storyline as he wanted more soap-opera-like storyline in the company at that time.
One more interesting twist in the tale was that this storyline was planned to introduce Scott Vick. However, it was later changed to Kane vs Triple H with the Big Red Machine being Katie Vick's boyfriend.
