To so many wrestling fans, the Royal Rumble PPV is the most exciting show of the year.
Granted, WrestleMania has the grandeur of being labelled the Showcase of the Immortals, the Grandest Stage of Them All, and has the PR machine sent into overdrive as that annual spectacular is positioned at WWE's most important, must-see PPV of the year. Yet there's something special about the Rumble and the possibilities it throws up.
Now, while the men's Royal Rumble match - and the women's Rumble match during its two years to date - has usually had an air of predictability to its winners, that's not to say that there haven't been some truly spectacular shocks delivered at the January PPV.
The majority of wrestling fans seem to be positioning Roman Reigns as the nailed-on favourite to win this year's men's Royal Rumble match, while Charlotte Flair or a returning Ronda Rousey look like the most likely options for the women's Rumble. But we're more interested in exploring some of the more out-there theories of what could play out this Sunday.
And remember, while these 10 theories may well be crazy, they also might just be crazy enough to come true.
