#6 Wrestlemania II was held on a Monday
By anyone's estimation, WrestleMania was a glorious mess of a pay per view.
For no readily discernible reason, the event was split between three separate venues. One part came live from New York City, another came from Rosemont Illinois, and the final part broadcast from Los Angeles, California.
This led to many difficulties with coordinating the three events and putting on the televised matches. No one knows why the WWE attempted such an ambitious, if bizarre, arrangement.
Even more bizarre than the three venues situation was the fact that Wrestlemania II was broadcast on a Monday. The WWE would abandon Monday night ppvs in favor of Sundays, and ever since WrestleMania has always happened on a Sunday.
But not WrestleMania II, the PPV that dares to be different.
