#1 Katie Vick

For wrestling fans, nothing makes them roll their eyes more than the mere mention of Katie Vick. It was during an episode of Raw that Triple H first mentioned her. Katie Vick was the supposed former girlfriend of WWE superstar Kane, who was apparently murdered by Kane.
The week after Triple H mentioned Katie Vick, Kane came out on Raw to explain that he killed Katie Vick in a drunk driving accident. Kane said he was behind the wheel and suffered injuries, but that Vick did not survive. As if this was not bad enough, it only got worse. On the next episode of Raw, Triple H fondled a mannequin in a casket, presumably Katie Vick.
I'm not sure what the creative team was smoking at the time, but the idea of your top wrestler molesting a mannequin in a casket isn't a good idea on any drug. The storyline only lasted a couple more weeks before it was forgotten about. However, it's become one of the biggest faux pas in the history of wrestling.
