#1. Hulk Hogan - WrestleMania IX
This tops the list because if WWE pulled something like this off at WrestleMania in the modern era, they would get severe backlash. It was WrestleMania IX in 1993 and the young Bret Hart was set to headline the show in a WWE Title defense against Yokozuna.
Bret Hart was informed a day earlier that he would be dropping the Title to Yokozuna. And despite the fact that he was upset about it, he would try to make it the best main event that he could.
After getting blinded by Mr. Fuji, Bret Hart lost the WWE Championship to Yokozuna. Right after, Hulk Hogan would make an appearance to "save the day" (despite losing his match earlier that evening) and proceed to beat Yokozuna in less than half a minute.
It was a huge waste of a WrestleMania main event. Hulk Hogan never gave Bret Hart the "passing of the torch" match that he deserved that year and instead dropped the WWE Title right back to Yokozuna - who would embark on a lengthy reign before Bret Hart received his coronation at WrestleMania 10 the following year.
