It’s hard being a wrestling fan.
David Arquette winning the WCW World Heavyweight Championship.
While promoting his wrestling-themed film Ready To Rumble in 2000, David Arquette appeared on WCW and ended up winning the World Heavyweight Championship. That's right, the same belt that names like Hulk Hogan, Ric Flair, Sting, and Vince Russo had held. Arquette's 12 day reign came to an end with him losing the title in a Triple Cage (lol classic Russo) to Jeff Jarrett. Many say that this was one of the final nails in the coffin for WCW which was ultimately purchased by WWF/E less than a year later.

The Katie Vick incident.
In 2002, Triple H and Kane began a feud that would lead to one of the worst/embarrassing/all-round fucked up segments in WWE Raw's 20+ year run. Triple H would expose that Kane was in love with a girl named Katie Vick when he was younger, but Katie did not love him back. In the weeks that followed it was revealed that Vick had died in a car accident. This lead to a segment taking place at an open-casket funeral where Triple H, dressed as Kane, would grope the dead body and proceed to have sex with it. That happened 12 years ago and many still wonder how it was considered a good idea.

The Claire Lynch/AJ Styles pregnancy angle.
Crazy lady comes out of the blue, tells AJ Styles that she is carrying his baby, still one of the worst storylines in wrestling today.
TNA
The Undertaker kidnapping Theodore Long.
Bad camera angles, bad acting, corny effects. Needs no further explanation than this amazingly cringe-worthy GIF.
