10 Best Kept Secrets In Wrestling History

10. John Cena's Royal Rumble Return

A return so deeply shocking and exciting, 20,000 folks briefly forgot it wasn't cool to love John Cena during the late 2000's. Wonderful stuff.

After going down injured in October 2007 with a pectoral tear, most expected to not see 'The Face that Runs the Place' for around six months to a year. But this freak of nature isn't your average human, folks.

About a month before his sensational comeback inside of Madison Square Garden during the 2008 Royal Rumble, folks within the company were already aware one of the most unlikeliest of comebacks was on, according to Bruce Prichard on his Something to Wrestle pod (via 411Mania).

And then, when the time came to execute this monumental surprise at the PPV, former WWE referee Marty Elias recalled to Wrestling Inc how WWE went to extreme lengths to keep this unexpected secret. Cena was hidden all day, and even marched through the hallway covered when the time came to finally blow the roof off of MSG.

All that effort to keep this Rumble return under wraps paid off and then some in the end, with Cena's number #30 entrance at the event producing one of the most authentic sounds of unfiltered shock you'll ever hear on a wrestling show.
